Changes from NEWS:

## GNU ZRTP 4.6.6 ##

Small fix in zrtp/crypto/zrtpDh.cpp to fix a small memory leak.


## GNU ZRTP 4.6.5 ##

Cleanup compiler flags, reduce visibility for Android build,
check some buffer length. No functional enhancements, no changes
in API.


## GNU ZRTP 4.6.4 ##

Some fixes to slience Windows C/C++ compiler, fix a few include
statements when using openSSL, small fixes to check disclosure
flag. Reset valid flags when adding a new cache record to avoid
wrong security message.


## GNU ZRTP 4.6.3 ##

A small fix inside the ZRTP main module to ignore malformed
DH1 packets and avoid an NULL pointer access.


## GNU ZRTP 4.6.2 ##

A small fix in the ZrtpCWrapper to fix an issue within 4.6.1
;-)


## GNU ZRTP 4.6.1 ##

A small fix in the ZrtpCWrapper to initialize and use the ZRTP
master instance in case of multi-stream usage. Does not affect
the main ZRTP usage, only projects that use the wrapper such
as PJSIP or Gstreamer projects.

These project should re-compile if they use the multi-stream
feature.


## GNU ZRTP 4.6.0 ##

Only a small add-on to the code to implement handling of the
disclosure flag. See RFC6189, chapter 11 for more details
about the disclosure flag.

Because the API changed, thus it's necessary to recompile
applications that use the new library version.


## GNU ZRTP 4.5.0 ##

Added a new SAS algorithm 'B32E' that uses 32 Unicode Emoji
code points instead of 32 ASCII characters. Application that
are able to display Emojis may use this new SAS algorithm to
display nice Emojis instead of 'boring' ASCII letters and
digits.

Some technical details:

* the 32 selected emojis are easily distinguishable, known to
  everyone, not offending etc, and use standard Unicode code
  points
* select colored emojis that look good on white and on black
  backgrounds (most emojis look good on white only)
* select emojis that are available on iOS, Android, Mac OS X
  (Windows not checked)
* the resulting SAS string is UTF-8 encoded, suitable for most
  platforms except Java.

To use the codes for Java the application needs to translate the
UTF-8 encoding into UTF-16 encoding. Because most of the emojis
are Unicode supplementary characters the UTF-8 to UTF-16 conversion
must generate the necessary UTF-16 surrogate pairs.

To support the UTF-8 / UTF-16 conversion the common directory
contains conversion functions that I extracted from ICU C/C++
library source.

Because the API changed, thus it's necessary to recompile
applications that use the new library version.

From NEWS:

== GNU ZRTP 4.4.0 ==

Changes the handling of HMAC and Hash contexts to avoild tool
many malloc/free calls and thus memory pointer problems.

Enhance the handling an check the nonce when using multi-stream
mode. This required a modification to the class file and some
modifications on the API. The old functions are now deprecated
but still usable. Nevertheless you should change your application
to use the new fuctions which support the new nonce handling and
checks.

Some bug fixing as well.

== GNU ZRTP 4.3.1 ==

This is a bugfix release. It fixes several compiler issues in
iOS8 Clang, Mircosoft C++ compiler (VS 2012) etc.

This release also adds a fix to address a possible problem when
using 'memset(...)' on a memory area immediately followed by a
'free(...)' call to free this memory area. Some compilers may
otpimize the code and do not call 'memset(...)'. That's bad for
software that deals with secure keys :-) . The fix removes this
possible vulnerability.


== GNU ZRTP 4.3.0 ==

This version adds some new API that provide to set retry timer
values and to get some retry counters.

Application may now set some values of the retry counters during
the discovery (Hello) and the negotiation phase. Applications may
increase the number of retries or modify the capping to support
slow or bad networks.

To get some idea about the actual number of retries during ZRTP
negotiation an application may now use the new API to get an array
of counters. The ZRTP state engine records how many retries occured
during the different protocol states.

Note: only the ZRTP initiator performs packet retries after the
discovery (Hello) phase. The responder would always return zero
alues for the other retry counters.

Because we have a new set of functions the API changed, thus it's
necessary to recompile applications that use the new library version.


== GNU ZRTP 4.2.4 ==

Only small changes to enable Android X86 (see clients/tivi/android)
as an example.

Rename functions aes_init() to aes_init_zrtp() to avoid names clashes
with other libreries that may include own AES modules.


== GNU ZRTP 4.2.3 ==

The optional SAS relay feature (refer to RFC6189, chapter 7.3) is
not longer compiled by default. If your project needs this support
then modify the CMakeLists.txt file and uncomment a 'add_definition'
statments. See comment in the CMakelists.txt file.

The reasons to disable this optional feature in the default build:
it's rarely used and some concerns about misusing this feature.


== GNU ZRTP 4.2.2 ==

A small enhancement in SRTP handling to provide a longer bit-shift
register with 128 bits. The replay now check accepts packets which
are up to 127 sequence number behing the current packet. The upper
layer (codecs) gets more packets on slower/bad networks that we may
see on mobile 3G/4G connections.

If the codecs do not remove silence then this may lead to some longer
audio replay, similar to sattelite communication.


== GNU ZRTP 4.2.1 ==

Bug fixes in the SRTP part that checks for replay and updates the ROC.

The wrong computations lead to false replay indications and to wrong
HMAC, thus they dropped to much packets, in particular under bad network
conditions.

Changed the handling the the zrtp_getSasType function the the ZrtpCWrapper.
Please check the inline documentation and the compiler warning how to
use the return value of the function.

Updated to latest release, 4.2.0. Shared library name change. From NEWS:

Implemented a new function to read the ZID file if the ZID file backend
is SQlite3. This is not a security problem because the ZRTP cache was
always public and readable, refer to RFC6189.

SQL statement returns all ZID records, sorted by date, newest on top. The
function can then step thru the DB cursor and read the records.

The version also include sevral fixes, usually compiler warnings, some
small problems reported by 'cppcheck' analyser.

Because we have a new set of functions the API changed, thus it's necessary
to recompile applications that use the new library version.

Updated to latest release, 4.1.2. Resolves:
http://secunia.com/advisories/53818/ From NEWS:
== GNU ZRTP 4.1.1 ==

Is a bug fix release that fixes some problems when building a standalone
version of the library, i.e. with embedded crypto algorithms and not using
on openSSL.

Another fix was necessary for NetBSD thread handling.


== GNU ZRTP 4.1.0 ==

Small enhancements when dealing with non-NIST algorithms. An application may
set a ''algorithm selection policy'' to control the selection behaviour. In
addition the the standrad selection policy (as per RFC6189) this version
provides a _non-NIST_ selection policy: if the selected public key algorithm
is a non-NIST ECC algorithm then the other selection functions prefer non-NIST
HASH algorithms (Skein etc).


== GNU ZRTP 4.0.0 ==

For this version I added some new algorithms for the DH key agreement
and the Skein Hash for ZRTP. Not further functional enhancments.

Added a new (old) build parameter -DCORE_LIB that will build a ZRTP core
library. This was available in V2.3 but I somehow lost this for 3.0
You may add other build parameters, such as SQLITE and CRYPTO_STANDALONE
if you build the core library.


== GNU ZRTP 3.2.0 ==

The main ZRTP modules contain fixes for three vulnerabilities found by Mark
Dowd. Thus we advise application developers to use this version of the
library. The vulnerabilities may lead to application crashes during ZRTP
negotiation if an attacker sends prepared ZRTP packets. The fixes remove these
attack vectors.

Some small other enhancements and cleanup, mainly inside client code.

Some enhancements in cache handling and the handling of retained shared
secrets. This change was proposed by Phil, is a slight security enhacement and
is fully backward comaptible.

Because of some API changes clients must be compiled and linked with the new
library.

For details please refer to the Git logs.


== GNU ZRTP 3.1.0 ==

This version adds some new features and code that supports some other
client and this accounts for the most changes inside this release.

The ZRTP core functionality was not changed as much (bug fixes, cleanup
mainly) and remains fully backward compatible with older library
versions. However, one nice enhancement was done: the addition of a standalone
SDES support module. This module supports basic SDES only without the fancy
stuff like many other SDES implementations. Thus it's pretty interoperable.

Some other features are:
- add some android support for a client, may serve as template for others
- documentation and code cleanup

Because of some API changes clients must be compiled and linked with the new
library.


== GNU ZRTP 3.0.0 ==

This is a major enhancement and restructuring of the overall ZRTP
distribution. This was necessary because more and more other clients use ZRTP
and add their specific glue code. Also some clients are not prepared to use
openSSL or other crypto libraries to their code and distributions.

Here a summary of the changes
- a new directory layout to accomodate various clients
- add standalone crypto modules, for example for AES, to have a real
  standalone ZRTP/SRTP library that does not require any other crypto library
  (optional via CMake configuration)
- Re-structure ZRTP cache and add SQlite3 as optional storage backend

The default settings for CMake build the normal ZRTP library that use openSSL
as crypto backend, use the normal file based cache and include the GNU ccRTP
modules. This is a librray that is to a large degree compatible with the
earlier builds.

Please refer to the top level CMakeFile.txt for options how to switch on the
standalone crypto mode or the SQlite3 based cache storage.

Updated to latest release. No functional differences in pkgsrc files. From
ChangeLog:
2.3.3:

- fallback to gcrypt if no openssl elliptical support

Import libzrtpcpp-2.3.2 as net/libzrtpcpp.

libzrtpcpp, a separate extension package to ccrtp, provides support for the ZRTP
protocol (as defined in the Internet draft draft-zimmermann-avt-zrtp).
