Hashing algorithms for password storage

[bauen1]

Storing passwords in databases #7 should not be done in cleartext, but carbon doesn't provide any hashing algorithms at the moment, for example sha256 and sha512.
Some other cryptographic algorithms that could be added are AES or the RSA algorithm

Nice request, I like it.

I'll probably implement it soon, however, currently, I want to make sure the things I already have work correctly. Maybe for 1.3.1, if it doesn't make it into 1.3 (Or 1.4, if I decide to skip 1.3 because of the many many changes...)?
