-Changelog
-
-1.3.20
-
-  Lots of changes.  Thanks to Jeff Chan for catching a memory leak and
-  helping track down the endian issues with the SSRCs.
-
-1.3.8
-
-  This is an interim release.  Several little-endian bugs were identified
-  and fixed; this means that we can use intel/linux for development again.
-
-  Cleaned up sha1 and hmac code significantly, got rid of some excess
-  functions and properly documented the fuctions in the .h files.
-
-  Eliminated some vestigial files.
-
-  There is a SIGBUS error in the AES encrypt function on sparc
-  (observed on both solaris and openbsd) with gcc 2.95.  Was unable to
-  find bad pointer anywhere, so I'm wondering if it isn't a compiler
-  problem (there's a known problem whose profile it fits).  It doesn't
-  appear on any other platform, even in the cipher_driver stress
-  tests.
-
-  Planned changes
-
-  Change interface to nonces (xtd_seq_num_t) so that it uses
-  network byte ordering, and is consistent with other arguments.
-
-
-1.3.6 
-
-  Changed /dev/random (in configure.in and crypto/rng/rand_source.c) to
-  /dev/urandom; the latter is non-blocking on all known platforms (which 
-  corrects some programs that seem to hang) and is actually present on 
-  Open BSD (unlike /dev/random, which only works in the presence of 
-  hardware supported random number generation).
-
-  Added machine/types.h case in include/integers.h.
-
-1.3.5
-
-  Removing srtp_t::template and stream_clone().
-
-  Adding a new policy structure, which will reflect a complete SRTP
-  policy (including SRTCP).
-
-  This version is *incomplete* and will undergo more changes.  It is
-  provided only as a basis for discussion.
-
-1.3.4
-
-   Removed tmmh.c and tmmh.h, which implemented version one of TMMH.
-
-   Changed srtp_get_trailer_length() to act on streams rather than
-   sessions, and documented the macro SRTP_MAX_TRAILER_LEN, which should
-   usually be used rather than that function.
-
-   Removed 'salt' from cipher input. 
-
-   Changed rdbx to use err.h error codes.
-
-   Changed malloc() and free() to xalloc() and xfree; these functions
-   are defined in crypto/kernel/alloc.c and declared in 
-   include/alloc.h.
-
-   Added 'output' functions to cipher, in addition to 'encrypt'
-   functions.  It is no longer necessary to zeroize a buffer before
-   encrypting in order to get keystream.
-
-   Changed octet_string_hex_string() so that "times two" isn't needed
-   in its input.
-
-   Added crypto_kernel_init() prior to command-line parsing, so that
-   kernel can be passed command-line arguments, such as "-d
-   debug_module".  This was done to for the applications
-   test/srtp-driver, test/kernel-driver, and test/ust-driver.
-
-   Improved srtp_init_aes_128_prf - wrote key derivation function
-   (srtp_kdf_t).
-
-   Add the tag_len as an argument to the auth_compute() function, but
-   not the corresponding macro.  This change allows the tag length for
-   a given auth func to be set to different values at initialization
-   time.  Previously, the structure auth_t contained the
-   output_length, but that value was inaccessible from hmac_compute()
-   and other functions.
-
-   Re-named files from a-b.c to a_b.c. in order to help portability.
-
-   Re-named rijndael to aes (or aes_128 as appropriate).
-
-
-1.2.1 
-
-  Changes so that 1.2.0 compiles on cygwin-win2k.
-
-  Added better error reporting system.  If syslog is present on the
-  OS, then it is used.
-
-
-1.2.0 Many improvements and additions, and a fex fixes
-
-   Fixed endian issues in RTP header construction in the function
-   rtp_sendto() in srtp/rtp.c.
-
-   Implemented RIJNDAEL decryption operation, adding the functions
-   rijndael_decrypt() and rijndael_expand_decryption_key().  Also
-   re-named rijndael_expand_key() to rijndael_expand_encryption_key()
-   for consistency.
-
-   Implemented random number source using /dev/random, in the files
-   crypto/rng/rand_source.c and include/rand_source.h.
-
-   Added index check to SEAL cipher (only values less than 2^32 are
-   allowed)
-
-   Added test case for null_auth authentication function.
-
-   Added a timing test which tests the effect of CPU cache thrash on
-   cipher throughput.  The test is done by the function
-   cipher_test_throughput_array(); the function
-   cipher_array_alloc_init() creates an array of ciphers for use in
-   this test.  This test can be accessed by using the -a flag to
-   the application cipher-driver in the test subdirectory.
- 
-   Added argument processing to ust-driver.c, and added that app to
-   the 'runtest' target in Makefile.in.
-
-   A minor auth_t API change: last argument of auth_init() eliminated.
-
-
-1.0.6 A small but important fix
-
-   Fixed srtp_init_aes_128_prf() by adding octet_string_set_to_zero()
-   after buffer allocation.
-
-   Eliminated references to no-longer-existing variables in debugging
-   code in srtp/srtp.c.  This fixes the compilation failure that
-   occured when using PRINT_DEBUG in that file.
-
-   Corrected spelling of Richard Priestley's name in credits.  Sorry
-   Richard!
-
-
-1.0.5 Many little fixes
-
-   Fixed octet_string_set_to_zero(), which was writing one
-   more zero octet than it should.  This bug caused srtp_protect()
-   and srtp_unprotect() to overwrite the byte that followed the
-   srtp packet.
-
-   Changed sizeof(uint32_t) to srtp_get_trailer_length() in
-   srtp-driver.c.  This is just defensive coding.
-
-   Added NULL check to malloc in srtp_alloc().
-
-
-1.0.4 Many minor fixes and two big ones (thanks for the bug reports!)
-
-   Removed 'ssrc' from the srtp_init_aes_128_prf() function argument
-   list.  This is so that applications which do not a priori know the
-   ssrc which they will be receiving can still use libsrtp.  Now the
-   SSRC value is gleaned from the rtp header and exored into the
-   counter mode offset in the srtp_protect() and srtp_unprotect()
-   functions, if that cipher is used.  This change cascaed through
-   many other functions, including srtp_init_from_hex(),
-   srtp_sender_init() and srtp_receiver_init() in rtp.c, and also
-   changing the CLI to test/rtpw.  In the future, another function
-   call will be added to the library that enables multiple ssrc/key
-   pairs to be installed into the same srtp session, so that libsrtp
-   works with multiple srtp senders.  For now, this functionality is
-   lacking.
-
-   Removed the GDOI interface to the rtpw demo program.  This will be
-   added again at a later date, after the SRTP and GDOI distributions
-   stabilize.  For now, I've left in the GDOI #defines and autoconf
-   definitions so that they'll be in place when needed.
-
-   Updated tmmhv2_compute() so that it didn't assume any particular
-   alginment of the output tag.
-
-   Changed bit field variables in srtp.h to unsigned char from
-   unsigned int in order to avoid a potential endianness issue.
-
-   Fixed rdbx_estimate_index() to handle all input cases.  This solves
-   the now notorious "abaft" bug in the rtpw demo app on linux/intel,
-   in which spurious replay protection failures happen after that word
-   is received.
-
-   Added ntohs(hdr->seq) to srtp_protect and srtp_unprotect, removed
-   from rijndael_icm_set_segment().
-
-   Added error checking and handling to srtp_sender_init() and
-   srtp_receiver_init().
-
-   Changed srtp_alloc() so that it does what you'd expect: allocate an
-   srtp_ctx_t structure.  This hides the library internals.
-
-
-1.0.1   Many minor fixes
-
-   Added cipher_driver_buffer_test(...) to test/cipher-driver.c.  This
-   function checks that the byte-buffering functions used by a cipher
-   are correct.
-
-   Fixed SunOS/Solaris build problems: added HAVE_SYS_INT_TYPES_H and
-   changed index_t to xtd_seq_num_t (see include/rdbx.h).
-
-   Fixed SEAL3.0 output byte buffering, added byte-buffering test to
-   cipher/cipher-driver.c.
-
-   Fixed roc-driver so that the non-sequential insertion test
-   automatically recovers from bad estimates.  This was required to
-   prevent spurious failures.
-
-   Made rdbx_estimate_index(...) function smarter, so that initial RTP
-   sequence numbers greater than 32,768 don't cause it to estimate the
-   rollover counter of 0xffffffff.
-
-
-1.0.0   Initial release

-Secure RTP (SRTP) Reference Implementation
-David A. McGrew
-Cisco Systems, Inc.
-mcgrew@cisco.com
-
-
-This package provides an implementation of the Secure Real-time
-Transport Protocol (SRTP), the Universal Security Transform (UST), and
-a supporting cryptographic kernel.  These mechanisms are documented in
-the Internet Drafts in the doc/ subdirectory.  The SRTP API is
-documented in include/srtp.h, and the library is in libsrtp.a (after
-compilation).  An overview and reference manual is available in
-doc/libsrtp.pdf.  The PDF documentation is more up to date than this
-file.
-
-
-Installation:
-
-./configure [ options ]       # GNU autoconf script 
-make                          # or gmake if needed; use GNU make
-
-The configure script accepts the following options:
-
-   --help              provides a usage summary
-   --disable-debug     compile without the runtime debugging system
-   --enable-syslog     use syslog for error reporting
-   --disable-stdout    use stdout for error reporting
-   --enable-console    use /dev/console for error reporting
-   --gdoi              use GDOI key management (disabled at present)
-
-By default, debbuging is enabled and stdout is used for debugging.
-You can use the above configure options to have the debugging output
-sent to syslog or the system console.  Alternatively, you can define
-ERR_REPORTING_FILE in include/conf.h to be any other file that can be
-opened by libSRTP, and debug messages will be sent to it.  
-
-This package has been tested on Mac OS X (powerpc-apple-darwin1.4),
-Cygwin (i686-pc-cygwin), and Sparc (sparc-sun-solaris2.6).  Previous
-versions have been tested on Linux and OpenBSD on both x86 and sparc
-platforms.

-Applications
-
-  Several test drivers and a simple and portable srtp application
-  are included in the test/ subdirectory.
-
-  test driver	function tested	
-  -------------------------------------------------------------
-  kernel_driver crypto kernel (ciphers, auth funcs, rng)
-  srtp_driver	srtp in-memory tests (does not use the network)
-  rdbx_driver	rdbx (extended replay database)
-  roc_driver	extended sequence number functions 
-  replay_driver	replay database (n.b. not used in libsrtp)
-  cipher_driver	ciphers 
-  auth_driver	hash functions 
-
-  The app rtpw is a simple rtp application which reads words from
-  /usr/dict/words and then sends them out one at a time using [s]rtp.
-  Manual srtp keying uses the -k option; automated key management
-  using gdoi will be added later.
-
-usage: rtpw [-d <debug>]* [-k <key> [-a][-e]] [-s | -r] dest_ip dest_port
-or     rtpw -l
-
-  Either the -s (sender) or -r (receiver) option must be chosen.
-
-  The values dest_ip, dest_port are the ip address and udp port to
-  which the dictionary will be sent, respectively.  
-
-  options:
-
-  -s		(s)rtp sender - causes app to send words
-
-  -r		(s)rtp receive - causes app to receve words
-
-  -k <key>      use srtp master key <key>, where the
-		key is a hexadecimal value (without the
-                leading "0x")
-
-  -e            encrypt/decrypt (for data confidentiality)
-                (requires use of -k option as well)
-
-  -a            message authentication 
-                (requires use of -k option as well)
-
-  -l            list debug modules
-
-  -d <debug>    turn on debugging for module <debug>
-
-
-In order to get random 30-byte values for use as key/salt pairs , you
-can use the following bash function to format the output of
-/dev/random (where that device is available).
-
-function randhex() {
-   cat /dev/random | od --read-bytes=32 --width=32 -x | awk '{ print $2 $3 $4 $5 $6 $7 $8 $9 $10 $11 $12 $13 $14 $15 $16 }'
-}
-
-
-An example of an SRTP session using two rtpw programs follows:
-
-set k=c1eec3717da76195bb878578790af71c4ee9f859e197a414a78d5abc7451
-
-[sh1]$ test/rtpw -s -k $k -ea 0.0.0.0 9999 
-Security services: confidentiality message authentication
-set master key/salt to C1EEC3717DA76195BB878578790AF71C/4EE9F859E197A414A78D5ABC7451
-setting SSRC to 2078917053
-sending word: A
-sending word: a
-sending word: aa
-sending word: aal
-...
-
-[sh2]$ test/rtpw -r -k $k -ea 0.0.0.0 9999 
-security services: confidentiality message authentication
-set master key/salt to C1EEC3717DA76195BB878578790AF71C/4EE9F859E197A414A78D5ABC7451
-19 octets received from SSRC 2078917053 word: A
-19 octets received from SSRC 2078917053 word: a
-20 octets received from SSRC 2078917053 word: aa
-21 octets received from SSRC 2078917053 word: aal
-...
-
-Implementation Notes
-
-  * The srtp_protect() function assumes that the buffer holding the
-    rtp packet has enough storage allocated that the authentication 
-    tag can be written to the end of that packet.  If this assumption
-    is not valid, memory corruption will ensue.  
-
-  * Automated tests for the crypto functions are provided through
-    the cipher_type_self_test() and auth_type_self_test() functions.
-    These functions should be used to test each port of this code 
-    to a new platform.
-
-  * Replay protection is contained in the crypto engine, and
-    tests for it are provided.
-
-  * This implementation provides calls to initialize, protect, and
-    unprotect RTP packets, and makes as few as possible assumptions
-    about how these functions will be called.  For example, the
-    caller is not expected to provide packets in order (though if
-    they're called more than 65k out of sequence, synchronization
-    will be lost).
-    
-  * The sequence number in the rtp packet is used as the low 16 bits
-    of the sender's local packet index. Note that RTP will start its
-    sequence number in a random place, and the SRTP layer just jumps
-    forward to that number at its first invocation.  An earlier
-    version of this library used initial sequence numbers that are
-    less than 32,768; this trick is no longer required as the
-    rdbx_estimate_index(...) function has been made smarter.
-
-  * The replay window is 128 bits in length, and is hard-coded to this
-    value for now.

-    STATIC LIBRARY : srtp Project Overview
-========================================================================
-
-AppWizard has created this srtp library project for you.
-
-No source files were created as part of your project.
-
-
-srtp.vcproj
-    This is the main project file for VC++ projects generated using an Application Wizard.
-    It contains information about the version of Visual C++ that generated the file, and
-    information about the platforms, configurations, and project features selected with the
-    Application Wizard.

-TODO List
-
-1.4.1
-
-  - document which fields are in NBO/HBO, and check for consistency.
-
-  - move HAVE_U_LONG_LONG inside of datatypes.c, or some other
-    separate file
-
-  - re-write configure.in to make cross-compilation easier
-
-  - eliminate GENERIC_AESICM by generalizing the code a bit
-
-Older comments
-
-  - add tests for key_limit_t datatype 
-
-  - move octet_get_weight() from datatypes.c to math.c (any other
-    funcs?)
-
-Changes and additions planned
-
-  Make cipher and auth dealloc() functions zeroize the key-storage
-  areas before calling free().
-
-  Eliminate key_len from auth_init()
-
-  Doucument internal APIs (cipher, auth, srtp_protect, ...)
-
-
-SRTP options not (yet) included in this libaray:
-
- - the aes-f8-mode cipher
- - the Master Key Index
- - re-keying using the key derivation function (only the initial
-   use of the PRF has been implemented, as it's sufficient
-   for most uses)
-
-
-(OLD) PLANNED CHANGES
-
-   strip out test/lfsr.c
-
-   Write new documentation!!!
-
-   Fix the x86 assembly code in aes.c.
-
-   Eliminate /* DAM */ - there's one in srtp.c
-
-   Change debugging so that it can print more than one line.  Or perhaps
-   just change it so that a single check of the debug-enabled flag is
-   needed.
-
-   Improve interface between cipher and rdbx - perhaps generalize rdbx
-   into 'nonce' datatype.
-
-   Make rijndael_icm accept variable sized keys.
-
-   Add rdbx functions that allow different-sized explicit sequence
-   numbers to be used.
-
-   Write uniform byte-buffering code for PRFs, preferably as macros.
-
-   Consider eliminating low-level alloc functions in favor of len()
-   functions, so that there need not be multiple allocations within a
-   particular alloc() function.

- * rollover counter and a sequence number; the sequence number is the
- * explicit part, and the rollover counter is the implicit part.
- *
- * Upon receiving a sequence_number (e.g. in a newly received SRTP
- * packet), the complete xtd_seq_num_t can be estimated by using a
- * local xtd_seq_num_t as a basis.  This is done using the function
- * index_guess(&local, &guess, seq_from_packet).  This function
- * returns the difference of the guess and the local value.  The local
- * xtd_seq_num_t can be moved forward to the guess using the function
- * index_advance(&guess, delta), where delta is the difference.
- * 
- *
- * A rdbx_t consists of a xtd_seq_num_t and a bitmask.  The index is highest
- * sequence number that has been received, and the bitmask indicates
- * which of the recent indicies have been received as well.  The
- * highest bit in the bitmask corresponds to the index in the bitmask.

- 
-@mainpage Introduction to libSRTP
- 
-This document describes libSRTP, the Open Source Secure RTP library
-from Cisco Systems, Inc.  RTP is the Real-time Transport Protocol, an
-IETF standard for the transport of real-time data such as telephony,
-audio, and video, defined by RFC 3550.  Secure RTP (SRTP) is an RTP
-profile for providing confidentiality to RTP data and authentication
-to the RTP header and payload.  SRTP is an IETF Proposed Standard,
-defined in RFC 3711, and was developed in the IETF Audio/Video
-Transport (AVT) Working Group.  This library supports all of the
-mandatory features of SRTP, but not all of the optional features.  See
-the @ref Features section for more detailed information.
- 
-This document is organized as follows.  The first chapter provides 
-background material on SRTP and overview of libSRTP.  The following
-chapters provide a detailed reference to the libSRTP API and related
-functions.  The reference material is created automatically (using the
-doxygen utility) from comments embedded in some of the C header
-files. The documentation is organized into modules in order to improve
-its clarity.  These modules do not directly correspond to files. An
-underlying cryptographic kernel provides much of the basic
-functionality of libSRTP, but is mostly undocumented because it does
-its work behind the scenes.
-

-@section Features Supported Features
-
-This library supports all of the mandatory-to-implement features of
-SRTP (as defined by the most recent Internet Draft).  Some of these
-features can be selected (or de-selected) at run time by setting an
-appropriate policy; this is done using the structure srtp_policy_t.
-Some other behaviors of the protocol can be adapted by defining an
-approriate event handler for the exceptional events; see the @ref
-SRTPevents section.  
-
-Some options that are not included in the specification are supported.
-Most notably, the TMMH authentication function is included, though it
-was removed from the SRTP Internet Draft during the summer of 2002.
-
-
-@latexonly
-Some options that are described in the SRTP specification are not
-supported.  This includes 
-\begin{itemize}
-\item the Master Key Index (MKI),
-\item key derivation rates other than zero,
-\item the cipher F8,
-\item anti-replay lists with sizes other than 128,
-\item the use of the packet index to select between master keys.
-\end{itemize}
-@endlatexonly
- 
-The user should be aware that it is possible to misuse this libary,
-and that the result may be that the security level it provides is
-inadequate.  If you are implementing a feature using this library, you
-will want to read the Security Considerations section of the Internet
-Draft.  In addition, it is important that you read and understand the
-terms outlined in the @ref LICENSE section.
-
-
-@section Installing Installing and Building libSRTP
-
-@latexonly
-
-To install libSRTP, download the latest release of the distribution
-from \texttt{srtp.sourceforge.net}.  The format of the names of the
-distributions are \texttt{srtp-A.B.C.tgz}, where \texttt{A} is the
-version number, \texttt{B} is the major release number, \texttt{C} is
-the minor release number, and \texttt{tgz} is the file
-extension\footnote{The extension \texttt{.tgz} is identical to
-\texttt{tar.gz}, and indicates a compressed tar file.}  You probably
-want to get the most recent release.  Unpack the distribution and
-extract the source files; the directory into which the source files
-will go is named \texttt{srtp}.
-
-libSRTP uses the GNU \texttt{autoconf} and \texttt{make}
-utilities\footnote{BSD make will not work; if both versions of make
-are on your platform, you can invoke GNU make as \texttt{gmake}.}.  In
-the \texttt{srtp} directory, run the configure script and then make:
-\begin{verbatim}
-  ./configure [ options ]       
-  make                          
-\end{verbatim}
-The configure script accepts the following options:
-\begin{quote}
-\begin{description}
-\item[--help]              provides a usage summary.
-\item[--disable-debug]     compiles libSRTP without the runtime 
-			   dynamic debugging system.
-\item[--enable-generic-aesicm] compile in changes for ismacryp
-\item[--enable-syslog]     use syslog for error reporting.
-\item[--disable-stdout]    diables stdout for error reporting.
-\item[--enable-console]    use \texttt{/dev/console} for error reporting
-\item[--gdoi]              use GDOI key management (disabled at present).
-\end{description}
-\end{quote}
-
-By default, dynamic debugging is enabled and stdout is used for
-debugging.  You can use the configure options to have the debugging
-output sent to syslog or the system console.  Alternatively, you can
-define ERR\_REPORTING\_FILE in \texttt{include/conf.h} to be any other
-file that can be opened by libSRTP, and debug messages will be sent to
-it.
-
-This package has been tested on the following platforms: Mac OS X
-(powerpc-apple-darwin1.4), Cygwin (i686-pc-cygwin), Solaris
-(sparc-sun-solaris2.6), RedHat Linux 7.1 and 9 (i686-pc-linux), and
-OpenBSD (sparc-unknown-openbsd2.7).

-@section Applications Applications
-
-@latexonly
-
-Several test drivers and a simple and portable srtp application are
-included in the \texttt{test/} subdirectory.
-
-\begin{center}
-\begin{tabular}{ll}
-\hline
-Test driver    	& Function tested	\\
-\hline
-kernel\_driver   & crypto kernel (ciphers, auth funcs, rng) \\
-srtp\_driver	& srtp in-memory tests (does not use the network) \\
-rdbx\_driver	& rdbx (extended replay database) \\
-roc\_driver	& extended sequence number functions \\ 
-replay\_driver	& replay database  \\
-cipher\_driver	& ciphers  \\
-auth\_driver	& hash functions \\
-\hline
-\end{tabular}
-\end{center}
-
-The app rtpw is a simple rtp application which reads words from
-/usr/dict/words and then sends them out one at a time using [s]rtp.
-Manual srtp keying uses the -k option; automated key management
-using gdoi will be added later.
-
-The usage for rtpw is
-
-\texttt{rtpw [[-d $<$debug$>$]* [-k $<$key$>$ [-a][-e]] [-s | -r] dest\_ip
-dest\_port] | [-l]}
-
-Either the -s (sender) or -r (receiver) option must be chosen.  The
-values dest\_ip, dest\_port are the IP address and UDP port to which
-the dictionary will be sent, respectively.  The options are:
-\begin{center}
-\begin{tabular}{ll}
-  -s		& (S)RTP sender - causes app to send words \\
-  -r		& (S)RTP receive - causes app to receive words \\
-  -k $<$key$>$      & use SRTP master key $<$key$>$, where the 
-		key is a hexadecimal value (without the
-                leading "0x") \\
-  -e            & encrypt/decrypt (for data confidentiality)
-                (requires use of -k option as well)\\
-  -a            & message authentication 
-                (requires use of -k option as well) \\
-  -l            & list the available debug modules \\
-  -d $<$debug$>$    & turn on debugging for module $<$debug$>$ \\
-\end{tabular}
-\end{center}
-
-In order to get a random 30-byte value for use as a key/salt pair, you
-can use the \texttt{rand\_gen} utility in the \texttt{test/}
-subdirectory.
-
-An example of an SRTP session using two rtpw programs follows:
-
-\begin{verbatim}
-[sh1] set k=`test/rand_gen -n 30`
-[sh1] echo $k
-c1eec3717da76195bb878578790af71c4ee9f859e197a414a78d5abc7451

-@section Review Secure RTP Background
-
-In this section we review SRTP and introduce some terms that are used
-in libSRTP.  An RTP session is defined by a pair of destination
-transport addresses, that is, a network address plus a pair of UDP
-ports for RTP and RTCP.  RTCP, the RTP control protocol, is used to
-coordinate between the participants in an RTP session, e.g. to provide
-feedback from receivers to senders.  An @e SRTP @e session is
-similarly defined; it is just an RTP session for which the SRTP
-profile is being used.  An SRTP session consists of the traffic sent
-to the SRTP or SRTCP destination transport addresses.  Each
-participant in a session is identified by a synchronization source
-(SSRC) identifier.  Some participants may not send any SRTP traffic;
-they are called receivers, even though they send out SRTCP traffic,
-such as receiver reports.
-
-RTP allows multiple sources to send RTP and RTCP traffic during the
-same session.  The synchronization source identifier (SSRC) is used to
-distinguish these sources.  In libSRTP, we call the SRTP and SRTCP
-traffic from a particular source a @e stream.  Each stream has its own
-SSRC, sequence number, rollover counter, and other data.  A particular
-choice of options, cryptographic mechanisms, and keys is called a @e
-policy.  Each stream within a session can have a distinct policy
-applied to it.  A session policy is a collection of stream policies.
-
-A single policy can be used for all of the streams in a given session,
-though the case in which a single @e key is shared across multiple
-streams requires care.  When key sharing is used, the SSRC values that
-identify the streams @b must be distinct.  This requirement can be
-enforced by using the convention that each SRTP and SRTCP key is used
-for encryption by only a single sender.  In other words, the key is
-shared only across streams that originate from a particular device (of
-course, other SRTP participants will need to use the key for
-decryption).  libSRTP supports this enforcement by detecting the case
-in which a key is used for both inbound and outbound data.
-
-
-@section Overview libSRTP Overview
-
-libSRTP provides functions for protecting RTP and RTCP.  RTP packets
-can be encrypted and authenticated (using the srtp_protect()
-function), turning them into SRTP packets.  Similarly, SRTP packets
-can be decrypted and have their authentication verified (using the
-srtp_unprotect() function), turning them into RTP packets.  Similar
-functions apply security to RTCP packets.
-
-The typedef srtp_stream_t points to a structure holding all of the
-state associated with an SRTP stream, including the keys and
-parameters for cipher and message authentication functions and the
-anti-replay data.  A particular srtp_stream_t holds the information
-needed to protect a particular RTP and RTCP stream.  This datatype
-is intentionally opaque in order to better seperate the libSRTP
-API from its implementation.
-
-Within an SRTP session, there can be multiple streams, each
-originating from a particular sender.  Each source uses a distinct
-stream context to protect the RTP and RTCP stream that it is
-originating.  The typedef srtp_t points to a structure holding all of
-the state associated with an SRTP session.  There can be multiple
-stream contexts associated with a single srtp_t.  A stream context
-cannot exist indepent from an srtp_t, though of course an srtp_t can
-be created that contains only a single stream context.  A device
-participating in an SRTP session must have a stream context for each
-source in that session, so that it can process the data that it
-receives from each sender.
-
-
-In libSRTP, a session is created using the function srtp_create().
-The policy to be implemented in the session is passed into this
-function as an srtp_policy_t structure.  A single one of these
-structures describes the policy of a single stream.  These structures
-can also be linked together to form an entire session policy.  A linked
-list of srtp_policy_t structures is equivalent to a session policy.  
-In such a policy, we refer to a single srtp_policy_t as an @e element.
-
-An srtp_policy_t strucutre contains two crypto_policy_t structures
-that describe the cryptograhic policies for RTP and RTCP, as well as
-the SRTP master key and the SSRC value.  The SSRC describes what to
-protect (e.g. which stream), and the crypto_policy_t structures
-describe how to protect it.  The key is contained in a policy element
-because it simplifies the interface to the library.  In many cases, it
-is desirable to use the same cryptographic policies across all of the
-streams in a session, but to use a distinct key for each stream.  A
-crypto_policy_t structure can be initialized by using either the
-crypto_policy_set_rtp_default() or crypto_policy_set_rtcp_default()
-functions, which set a crypto policy structure to the default policies
-for RTP and RTCP protection, respectively.
-				   
-@section Example Example Code
-
-This section provides a simple example of how to use libSRTP.  The
-example code lacks error checking, but is functional.  Here we assume
-that the value ssrc is already set to describe the SSRC of the stream
-that we are sending, and that the functions get_rtp_packet() and
-send_srtp_packet() are available to us.  The former puts an RTP packet
-into the buffer and returns the number of octets written to that
-buffer.  The latter sends the RTP packet in the buffer, given the
-length as its second argument.
-
-@verbatim
-   srtp_t session;   
-   srtp_policy_t policy;
-   uint8_t key[30];
-
-   // initialize libSRTP 
-   srtp_init();                                  
-
-   // set policy to describe a policy for an SRTP stream 
-   crypto_policy_set_rtp_default(&policy.rtp);   
-   crypto_policy_set_rtcp_default(&policy.rtcp); 
-   policy.ssrc = ssrc;                            
-   policy.key  = key;
-   policy.next = NULL;
-
-   // set key to random value 
-   crypto_get_random(key, 30);          
-
-   // allocate and initialize the SRTP session 
-   srtp_create(&session, &policy);  
-   
-   // main loop: get rtp packets, send srtp packets
-   while (1) {
-      char rtp_buffer[2048];
-      unsigned len;
-
-      len = get_rtp_packet(rtp_buffer);
-      srtp_protect(session, rtp_buffer, &len);
-      send_srtp_packet(rtp_buffer, len);
-   }
-@endverbatim
-
-@section ISMAcryp ISMA Encryption Support
-
-The Internet Streaming Media Alliance (ISMA) specifies a way 
-to pre-encrypt a media file prior to streaming.  This method
-is an alternative to SRTP encryption, which is potentially
-useful when a particular media file will be streamed
-multiple times.  The specification is available online 
-at  http://www.isma.tv/specreq.nsf/SpecRequest.
-
-libSRTP provides the encryption and decryption functions needed for ISMAcryp
-in the library @t libaesicm.a, which is included in the default
-Makefile target.  This library is used by the MPEG4IP project; see 
-http://mpeg4ip.sourceforge.net/.
-
-Note that ISMAcryp does not provide authentication for 
-RTP nor RTCP, nor confidentiality for RTCP.  
-ISMAcryp RECOMMENDS the use of SRTP message authentication for ISMAcryp
-streams while using ISMAcryp encryption to protect the media itself.
