Features
Note: Most of these features have been donated by Fox-IT
* Added Doxygen source code documentation parts
* Added generic message digest and cipher wrapper
for integration with OpenVPN
* Added reading of DHM context from memory and file
* Added verification callback on certificate chain
verification to allow external blacklisting
* Improved X509 certificate parsing to include extended
certificate fields, including Key Usage
* Improved certificate verification and verification
against the available CRLs
* Detection for DES weak keys and parity bits added
* Improvements to support integration in other
applications:
+ Added generic message digest and cipher wrapper
+ Improved information about current capabilities,
status, objects and configuration
+ Added verification callback on certificate chain
verification to allow external blacklisting
= Version 0.14.0 released on 2010-08-16
