Enum EcdsaSpec 

pub enum EcdsaSpec {
    Es256,
    Es384,
}

ECDSA algorithm specification.

Examples

use uselesskey_ecdsa::EcdsaSpec;

let es256 = EcdsaSpec::es256();
assert_eq!(es256.alg_name(), "ES256");
assert_eq!(es256.curve_name(), "P-256");

let es384 = EcdsaSpec::es384();
assert_eq!(es384.alg_name(), "ES384");
assert_eq!(es384.curve_name(), "P-384");

Variants

Es256

P-256 / secp256r1 / prime256v1 (for ES256 JWT signing).

Es384

P-384 / secp384r1 (for ES384 JWT signing).

Implementations

impl EcdsaSpec

pub fn es256() -> Self

Spec suitable for ES256 JWT signing.

Examples

use uselesskey_ecdsa::EcdsaSpec;

let spec = EcdsaSpec::es256();
assert_eq!(spec.alg_name(), "ES256");
assert_eq!(spec.curve_name(), "P-256");

pub fn es384() -> Self

Spec suitable for ES384 JWT signing.

Examples

use uselesskey_ecdsa::EcdsaSpec;

let spec = EcdsaSpec::es384();
assert_eq!(spec.alg_name(), "ES384");
assert_eq!(spec.curve_name(), "P-384");

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

Returns the JWT algorithm name.

Examples

use uselesskey_ecdsa::EcdsaSpec;

assert_eq!(EcdsaSpec::es256().alg_name(), "ES256");
assert_eq!(EcdsaSpec::es384().alg_name(), "ES384");

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

Returns the curve name.

Examples

use uselesskey_ecdsa::EcdsaSpec;

assert_eq!(EcdsaSpec::es256().curve_name(), "P-256");
assert_eq!(EcdsaSpec::es384().curve_name(), "P-384");

pub fn coordinate_len_bytes(&self) -> usize

Returns the expected coordinate length in bytes for uncompressed points.

Examples

use uselesskey_ecdsa::EcdsaSpec;

assert_eq!(EcdsaSpec::es256().coordinate_len_bytes(), 32);
assert_eq!(EcdsaSpec::es384().coordinate_len_bytes(), 48);

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_ecdsa::EcdsaSpec;

let bytes = EcdsaSpec::es256().stable_bytes();
assert_eq!(bytes.len(), 4);

Trait Implementations

impl Clone for EcdsaSpec

fn clone(&self) -> EcdsaSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EcdsaSpec

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

Formats the value using the given formatter.

impl Hash for EcdsaSpec

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

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 EcdsaSpec

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