pub enum HmacSpec {
    Hs256,
    Hs384,
    Hs512,
}

Specification for HMAC secret generation.

Variants

Hs256

HS256 (HMAC-SHA256)

Hs384

HS384 (HMAC-SHA384)

Hs512

HS512 (HMAC-SHA512)

Implementations

impl HmacSpec

pub fn hs256() -> HmacSpec

HS256 (HMAC-SHA256). Produces a 32-byte secret.

Examples

use uselesskey_core_hmac_spec::HmacSpec;
let spec = HmacSpec::hs256();
assert_eq!(spec.byte_len(), 32);

pub fn hs384() -> HmacSpec

HS384 (HMAC-SHA384). Produces a 48-byte secret.

Examples

use uselesskey_core_hmac_spec::HmacSpec;
let spec = HmacSpec::hs384();
assert_eq!(spec.byte_len(), 48);

pub fn hs512() -> HmacSpec

HS512 (HMAC-SHA512). Produces a 64-byte secret.

Examples

use uselesskey_core_hmac_spec::HmacSpec;
let spec = HmacSpec::hs512();
assert_eq!(spec.byte_len(), 64);

pub fn alg_name(&self) -> &'static str

JOSE/JWT alg name for this HMAC algorithm.

Examples

use uselesskey_core_hmac_spec::HmacSpec;
assert_eq!(HmacSpec::hs256().alg_name(), "HS256");

pub fn byte_len(&self) -> usize

Secret length, in bytes.

Examples

use uselesskey_core_hmac_spec::HmacSpec;
assert_eq!(HmacSpec::hs256().byte_len(), 32);
assert_eq!(HmacSpec::hs384().byte_len(), 48);
assert_eq!(HmacSpec::hs512().byte_len(), 64);

pub fn stable_bytes(&self) -> [u8; 4]

Stable encoding for cache keys / deterministic derivation.

If you change this, bump the derivation version in uselesskey-core.

Examples

use uselesskey_core_hmac_spec::HmacSpec;
let bytes = HmacSpec::hs256().stable_bytes();
assert_eq!(bytes.len(), 4);

Trait Implementations

impl Clone for HmacSpec

fn clone(&self) -> HmacSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HmacSpec

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

Formats the value using the given formatter.

impl Hash for HmacSpec

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HmacSpec

fn eq(&self, other: &HmacSpec) -> 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.
