Hi,
I posted the following message to the PostgreSQL mailing list, and one
of the main developers answered:

i have written a code for simple secure client server communication. i compile it on cygwin and run it on mips.
SSL_connect returns -1 and ERR_get_error(..) returns 0. and the error is SYS_ERROR_SYSCALL. errno is also 0.
could someone tell me why is this happening?

Personally, I'd like to see OpenSSL start using private key crypto as
hashing functions. The reason that work on dedicated hashing
algorithms kinda died off after MD[45]/SHA* came out was that people
figured out that they were the equivelent of private key encryption.

Given an encryption function c = f(k, p) where c is the resulting

Yeah, you need large key sizes- 128 bits keys just aren't enough (they
allow birthday attacks to be computationally feasible). But I note
that all the AES finalists went to 256 bit key sizes. This would put a
birthday attack at about 128 bits of complexity- sufficient. Anything

My point exactly. We don't need to panic- but I do think we need to start
looking for alternatives.

Careful. This is with MD5, a different (but still related) algorithm
To determine the probability of a birthday pairing, you need the probability
of each birthday pairing not having the same birthday taken to the exponent
of the number of pairings.
The probability of no birthday pairings for 27 people is
