Trait for password-based key derivation.

Required Associated Constants

const ALGORITHM: &'static str

Algorithm name.

Required Associated Types

type Params

Parameters type.

Required Methods

fn hash_password(password: &[u8], params: &Self::Params) -> Result<String>

Hash a password for storage.

Returns a string suitable for storage (includes salt and parameters).

fn verify_password(password: &[u8], hash: &str) -> Result<bool>

Verify a password against a stored hash.

fn derive_key( password: &[u8], salt: &[u8], params: &Self::Params, output_len: usize, ) -> Result<Vec<u8>>

Derive key material from password.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
