Pub Package Build Status Donate

A set of high-level APIs over PointyCastle to hash and verify passwords securely.
Heavily inspired on PHP's Password Hashing Functions.

Looking for two-way cryptography (encryption+decryption)? Please, visit encrypt.

API #

Password.hash #

Password.hash('password', new PBKDF2());
// $pcks$64,10000,64$530f8afbc74536b9a963b4f1c4cb738bcea7403d4d606b6e074ec5d3baf39d18$56158864e365bd78f6afda27f9a239bcb3f2b7a4773d4c0d0858c86266119d1e35aae9ca1a4777ed3d85c42caeed0c57cc7e09fe7d152d5d4d4ee08506c2b41a

Password.verify #

Password.verify('password', previousOutput);
// true

Password.verify('secret', previousOutput);
// false

Defaults #

In almost cases, you should rely on default PRNG for salts. It is cryptographically secure and unique for each password.

On the other hand, you are encouraged to change interations count for what your hardware can handle.
