Enum VerifyingKey 

#[non_exhaustive]
pub enum VerifyingKey {
    Ed25519(Box<VerifyingKey>),
    P256(Box<VerifyingKey<NistP256>>),
}

A public key that can verify.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ed25519(Box<VerifyingKey>)

An Ed25519 verifying key.

P256(Box<VerifyingKey<NistP256>>)

A P-256 verifying key.

Implementations

impl VerifyingKey

pub const fn algorithm(&self) -> Algorithm

The algorithm this key verifies.

pub fn to_raw_bytes(&self) -> Vec<u8>

The raw public key bytes: the 32-byte Ed25519 point, or the 65-byte uncompressed SEC1 encoding of a P-256 point.

The two are different lengths and neither is self-describing, so VerifyingKey::from_raw_bytes has to be told which algorithm it is reading. Prefer a Jwk anywhere the algorithm has to travel with the key.

pub fn from_raw_bytes( algorithm: Algorithm, bytes: &[u8], ) -> Result<VerifyingKey, JoseError>

Parses raw public key bytes for algorithm.

Errors

Returns JoseError::InvalidKey if the bytes are the wrong length for the algorithm, or are not a valid point.

pub fn verify(&self, message: &[u8], signature: &[u8]) -> Result<(), JoseError>

Verifies signature over message.

Errors

Returns JoseError::InvalidSignature if it does not verify.
