password_dart

Fork of password with null safety

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

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.

PBKDF2

PBKDF2(blockLength, iterationCount, desiredKeyLength, salt)

Default

Digest	SHA-512
Block size	64 bytes
Salt	32 bytes Fortuna
Iteration count	10000
Key length	64 bytes
