Few cleanups and couple of new things: - add SHA2 algorithm to older OpenSSL - add BIGNUM math to have public-key cryptography work on non-OpenSSL build. - gen_random_bytes() function The status of SHA2 algoritms and public-key encryption can now be changed to 'always available.' That makes pgcrypto functionally complete and unless there will be new editions of AES, SHA2 or OpenPGP standards, there is no major changes planned.
