Erlang cryptography module - ECDSA, RSA, SHA256 and so on

Question

I need a module that can generate keypairs, compute secure hashes and crypt and sign data. Is there any that module? Or maybe there is interface for OpenSSL crypto functions ?

Answer 1

sha2 modile for sha256

Answer 2

Read crypto module first. Now it's NIF since R14A so you can find out what sort of OpenSSL C functions are used.
