Struct Scrypt 

pub struct Scrypt { /* private fields */ }

Available on crate features kdf or mcf or phc only.

scrypt password hashing type which can produce and verify strings in either the Password Hashing Competition (PHC) string format which begin with $scrypt$, or in Modular Crypt Format (MCF) which begin with $7$.

This type holds the default parameters to use when computing password hashes.

See the toplevel documentation for a code example.

Implementations

impl Scrypt

pub const fn new() -> Self

impl CustomizedPasswordHasher<PasswordHash> for Scrypt

Available on crate feature phc only.

type Params = Params

Algorithm-specific parameters.

fn hash_password_customized( &self, password: &[u8], salt: &[u8], alg_id: Option<&str>, version: Option<Version>, params: Params, ) -> Result<PasswordHash>

fn hash_password_with_params( &self, password: &[u8], salt: &[u8], params: Self::Params, ) -> Result<H, Error>

Compute a password hash using customized parameters only, using the default algorithm and version.

impl Debug for Scrypt

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Scrypt

fn default() -> Scrypt

Returns the “default value” for a type.

impl From<Params> for Scrypt

fn from(params: Params) -> Self

Converts to this type from the input type.

impl Kdf for Scrypt

Available on crate feature kdf only.

fn derive_key(&self, password: &[u8], salt: &[u8], out: &mut [u8]) -> Result<()>

Writes uniformly random data suitable as key material into the entire length of out, derived from the following inputs:

impl PartialEq for Scrypt

fn eq(&self, other: &Scrypt) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Available on crate feature getrandom only.

Compute the hash H from the given password, potentially using configuration stored in &self for the parameters, or otherwise the recommended defaults.

fn hash_password_with_rng<R>( &self, rng: &mut R, password: &[u8], ) -> Result<H, Error>

where R: TryCryptoRng + ?Sized,

Available on crate feature rand_core only.
