If not, why not? http://stackoverflow.com/questions/16042128/is-this-a-good-hashing-password-function-in-php-if-not-why-not hashes in a given time good because it results in more computation being performed. So pbkdf2 is approximately 37.5 stronger than.. mainly because sha512 is a harder algorithm with more computation than md5 . This means that not only is pbkdf2 able to generate.. . This means that not only is pbkdf2 able to generate more computations in the same amount of time it's able to generate harder computations...

openssl_digest vs hash vs hash_hmac? Difference between SALT & HMAC? http://stackoverflow.com/questions/8952807/openssl-digest-vs-hash-vs-hash-hmac-difference-between-salt-hmac If you're doing so stop right now. The reason is simple computation time on a computer or GPU is incredibly cheap. It's so cheap.. And it's resistent to brute forcing since it's computationally expensive. Luckily it's available for PHP crypt password.. scrypt . It's better than bcrypt because it's just as computationally expensive but uses a LOT more memory on the order of 20mb..
