A small progress report update on the cryptographic developments. It is now possible to generate and validate certificates signed with DSA SHA1/SHA224/SHA256 and RSA MD2/MD5/SHA1/SHA256/SHA384/SHA512. I've successfully verified openssl certificates with the X509 module, and as a system test I've set up a TLS webserver with DSA certificate and had wget (using openssl) download from it. Besides the key generation, I feel that this part of the code is now in good shape.
