SHA256-CRYPT / SHA512-CRYPT in node.js

Question

I use dovecot as my mail transfer agent and I aim to use the strongest password scheme which is supported by my system: SHA512-CRYPT or SHA256-CRYPT

Answer 1

You may consider checking: https://github.com/mvo5/sha512crypt-node which contains a implementation for sha512crypt in JS. Its very new but passes the testvectors from the glibc reference implementation.
