It's 2016, so it's well worth revisiting this 5 year-old question. There was a Password Hashing Competition conducted from 2013 to 2016, which accepted 24 submissions and selected Argon2 as its recommended password hashing algorithm. Everything that Thomas said about new vs. good still applies. As recently as February 2016 (after the end of the contest) ...

SHA256crypt and SHA512crypt was described by Ulrich Drepper here. He provides an algorithm and implementation, but unfortunately not a security analysis, any proof that this algorithm is secure, or any insight in his design decisions. This makes it hard to analyze the security of the algorithm. The algorithm is pretty much like PBKDF2, in that it performs ...

There's three different password hashing algorithms being discussed here: | Algorithm | Cryptographic primitive | Crypto-currency that uses it| Miner speed | |-----------|-------------------------|-----------------------------|---------------| | PBKDF2 | SHA-256 | Bitcoin uses SHA-256 | 7 Thash/sec | | | ...
