Please see the OWASP Password Storage Cheat Sheet for assistance in selecting an appropriate algorithm for your use case.
The following code example shows how to verify a password when stored using one of many possible password hashing algorithms implemented in this repository.
use password_hash::{PasswordHash, PasswordVerifier};
use argon2::Argon2;
use pbkdf2::Pbkdf2;
use scrypt::Scrypt;
// Can be: `$argon2`, `$pbkdf2`, or `$scrypt`
let hash_string = "$argon2i$v=19$m=65536,t=1,p=1$c29tZXNhbHQAAAAAAAAAAA$+r0d29hqEB0yasKr55ZgICsQGSkl0v0kgwhd+U3wyRo";
let input_password = "password";
let password_hash = PasswordHash::new(&hash_string).expect("invalid password hash");
// Trait objects for algorithms to support
let algs: &[&dyn PasswordVerifier] = &[&Argon2::default(), &Pbkdf2, &Scrypt];
password_hash.verify_password(algs, input_password).expect("invalid password");MSRV bumps are considered breaking changes and will be performed only with minor version bump.
