If you want to upgrade to Argon2i before PHP 39 s password hashing API catches up the only way to do so is through libsodium. Most PBKDF2 implementations store a random salt with the password hash so you end up with a format like salt salted hash this is enough to force regeneration of every password and stop any rainbow tables from being used. I got the code to create hashes for password. The porting is almost always direct except for some classes that had been added to ease the use of low level data. If you want high level of security this should be replaced with password based key derivation function PBKDF2. 2013 Ensuite l 39 algorithme PBKDF2 Password Based Key Derivation Function est une fonction de d rivation de cl faisant partie des standards de nbsp 22 f vr.
