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.
produces garbage.
I learned the hard way that
#if UNDEFINED_1 == UNDEFINED_2
#error "gcc is idiot"
#endif
prints "gcc is idiot" ...
Affected are MD5/SHA1 in internal library, and also HMAC-MD5/HMAC-SHA1/
crypt-md5 which use them. Blowfish is ok, also Rijndael on at
least x86.
Big thanks to Daniel Holtzman who send me a build log which
contained warning:
md5.c:246: warning: `X' defined but not used
Yes, gcc is that helpful...
Please apply this.
