QCA is a library that provides an easy API for a range of cryptographic features, including SSL/TLS, X.509 certificates, SASL, OpenPGP, smartcards, and much more.
Functionality is supplied via plugins. This is useful for avoiding dependence on a particular crypto library and makes upgrading easier, as there is no need to recompile your application when adding or upgrading a crypto plugin.
In order for QCA to be of much use, you'll want to install some plugins.
QCA was originally created to support the security needs of the Psi XMPP/Jabber client project ( http://psi-im.org/ ).
API Documentation is located in the 'apidocs' subdirectory.
Have fun, -Justin
