PKCS#11 in Qt Cryptographic Architecture
Qt Cryptographic Architecture (QCA)
QCA is a cryptographic architecture for Qt toolkit. It abstracts the use of cryptographic API to ease cryptographic development. Any Qt application can use QCA, I hope that KDE 4.0 components will use QCA, so KDE 4.0 will be able to work with smartcards.
We won the "Qt Centre Programming Contest 2007" at "Helper Library" category, see here.
QCA Patches
PKCS#11 support is merged into QCA 2.0.
