Options for password hashing and key derivation.

Fields

iterations: u32

PBKDF2 iteration count.

time_cost: u32

Argon2 time cost.

memory_cost: u32

Argon2 memory cost in KiB.

parallelism: u32

Argon2 parallelism.

output_length: usize

Derived key length in bytes.

log_n: u8

scrypt log₂(N).

r: u32

scrypt block size parameter.

p: u32

scrypt parallelization parameter.

cost: u32

bcrypt cost factor.

Implementations

impl HashOptions

pub fn validate(&self) -> Result<()>

Validates that the cost parameters are internally consistent and above safe minimums. Called automatically by hash_with and [derive]; also usable standalone to check a hand-built struct.

Trait Implementations

impl Clone for HashOptions

fn clone(&self) -> HashOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HashOptions

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

Formats the value using the given formatter.

impl Default for HashOptions

fn default() -> Self

Returns the “default value” for a type.
