Pbkdf2_hmac python
SpletPassword hashing algorithms such as PBKDF2, bcrypt, and scrypt are meant for use with passwords and are purposefully slow. Cryptographic hashing algorithms are fast. Fast is good in most situations, but not here. Slowing down the algorithm (usually by iteration) make the attacker's job much harder.
