Well, I only know that I choose the best public cryptographic
algorithms.

SHA-2 has been designed by the National Security Agency (NSA), and I'm
sure that many people trust on the NSA so that every people make its
election.
But I'm sure that many people will avoid use algorithms recommend by
the governement. And I don't know why :P, they always say the truth
and we must trust on them. I'm sure that having great experts on
cryptography they are not bee able of put a backdoor indetectable or
better to debilitate the algorithm so that it is easier to break it.
