Qt Cryptographic Architecture
This package provides a generic Qt cryptographic architecture, including a library and a plug-in for using all supported capabilities of openssl, like SSL/TLS, X509, RSA, SHA1, MD5, Blowfish, 3DES, and AES.
It can be extended by further plug-ins, for example, with qca-sasl for SASL support.
