libsrtp is an implementation of the Secure Real-time Transport
Protocol (SRTP) originally authored by Cisco Systems, Inc.

SRTP is a security profile for RTP that adds confidentiality, message
authentication, and replay protection to that protocol. It is
specified in RFC 3711. More information about the SRTP protocol
itself can be found on the Secure RTP page.

%changelog
* Tue Aug  1 2017 jengelh@inai.de
- Update to new upstream release 2.1.0
  * Cipher type cleanup for AES. When libSRTP is compiled with
    OpenSSL and the AES 256 ICM cipher is used with RTCP, an
    incorrect initialization vector is formed. This change will
    break backwards compatibility with older versions (1.5, 2.0)
    of libSRTP when using the AES 256 ICM cipher with OpenSSL for
    RTCP.
  * Sequence number incorrectly masked for AES GCM IV. The
    initialization vector for AES GCM encryption was incorrectly
    formed on little endian machines. This change will break
    backwards compatibility with older versions (1.5, 2.0) of
    libSRTP when using the AES GCM cipher for RTCP.
  * Fix OOB read in key generation for encrypted headers with GCM
    ciphers. Adds padding of GCM salt to the corresponding ICM
    length used for header encryption. This change will break
    backwards compatibility with version 2.0 of libSRTP when
    using the header encryption extension with the AES GCM
    cipher.
  * Master Key Identifiers (MKI) Support - for 4 keys.
  * Report SSRC instead of srtp_stream_t in srtp_event_data_t.
  * Fix incorrect structure declarations for (S)RTP and (S)RTCP
    for big endian machines
* Mon Nov 21 2016 jengelh@inai.de
- Update to new 2.x generation, initial release 2.0.0
  * Massively smaller SDK, function names and types were cleaned
    and prefixed.
* Fri Mar  4 2016 sor.alexei@meowr.ru
- Update to 1.5.4:
  * Use BE byte ordering of RTCP trailer.
  * Allow zero length payload on unprotect.
* Fri Jan 22 2016 jengelh@inai.de
- Update to new upstream release 1.5.3
  * Maintenance release, including fix for CVE-2015-6360.
* Wed Jul 29 2015 dimstar@opensuse.org
- Add baselibs.conf: build libsrtp1-32bit, as needed by
  libmediastreamer_voip4-32bit.
* Sun Mar 15 2015 sor.alexei@meowr.ru
- Update to 1.5.2.
- Remove srtp-soname.diff as upstream now defines ABI in filenames
  correctly.
- Spec cleanup.
* Sat Jan  3 2015 jengelh@inai.de
- Update to new upstream release 1.5.0
  * Add support for OpenSSL crypto
  * Add support for AES-GCM crypto suites.
  * Add user data API to allow user to associate additional data
  with a SRTP context.
- Replace libsrtp-automake.patch by simpler srtp-soname.diff
* Thu Aug 28 2014 jengelh@inai.de
- Relax build restrictions for SLE11 (needs BuildRequires xz to
  even start, and we can drop dist-xz from the suggestive patch
  so that automake ~1.10)
* Tue Aug 26 2014 jengelh@inai.de
- Update project metadata, and patch description
* Wed Sep 18 2013 sbrabec@suse.cz
- Upgrade to the latest git snapshot of the version 1.4.5 from the
  new Cisco GIT repository:
  * support for Encrypted Key Transport (EKT)
  * AES-256 support
  * support for packet retransmission
  * API and ABI changes to support new features
  * many bug, crash and memory corruption fixes
  * several security fixes (CVE-2013-2139, bnc#828009)
- Increment shared library version, there are incompatible API and
  ABI changes.
- Rename the package to libsrtp, as did the upstream
- Port and rename srtp-automake.diff to libsrtp-automake.patch.
- Fix headers to not point to private not installed files
  (bnc#839475).
* Wed Oct 31 2012 jengelh@inai.de
- Fold the pkgconfig file into srtp-automake.diff
- Have libsrtp-devel depend on library package
* Wed Oct 31 2012 mailaender@opensuse.org
- Have the package provide a pkg-config file, and run ldconfig
  for the library package
* Tue Oct 25 2011 jengelh@medozas.de
- Remove redundant %%clean section
- Add automake patch so as to properly create shared libraries
* Tue Mar  8 2011 chris@computersalat.de
- spec-cleaner
- remove author from description
- rpmlint: wrong-file-end-of-line-encoding
* Sat Aug  8 2009 alexandre@exatati.com.br
- Version update to 1.4.4 and bzipped source.
  o sorry but CHANGES file is outdated
* Mon Jan 28 2008 sbrabec@suse.cz
- Generate package named srtp-devel.
* Tue Jun  5 2007 ro@suse.de

* Wed Jun 28 2006 sbrabec@suse.cz
- New SuSE package, version 1.4.2.
