Password Hashing: PBKDF2 (using sha512 x 1000) vs Bcrypt

WebbPBKDF2 is a key derivation function that uses a hash algorithm within it. Most implementations will select SHA1 or an SHA2-family algorithm. The important difference between you manually iterating through SHA1 a few thousand times and PBKDF2 is that PBKDF2 has been properly designed and scrutinized by cryptographers. – WebbRFC 7914 scrypt PBKDF August 2016 13.
