It has been a while since I blogged - a bit too much real-world work, plus a concerted effort on the Qt Cryptographic Architecture (QCA) are to blame.
Right now, I have QCA2 running, I have two plugin providers working - one based on OpenSSL, and the other based on GNU libgcrypt, and I have 595 passing unit tests. I'm particularly proud of the unit tests, because they give me a lot of confidence in the plugins. In terms of functionality, we have hashing (MD2, MD4, MD5, SHA0, SHA1, SHA256, SHA384, SHA512 and RIPEMD160), keyed hashes (HMAC-SHA1, HMAC-MD5 and HMAC-RIPEMD160) and some ciphers (AES128, AES192 and AES256 in ECB, CBC and CFB modes). Supporting that we have a basic random number provider, a secure byte array, and some arbitrary precision integer classes. It isn't really ready for prime time, but its emerging nicely.
