Struct ed448_verifier::verifying::VerifyingKey

pub struct VerifyingKey { /* private fields */ }

Ed448 public key.

Optionally implements

• signature::Verifier: if the “sha3” feature is enabled (default).
• signature::DigestVerifier: if the “sha3” and “digest” features are enabled.

Example

Please see the verifying module.

Implementations

impl VerifyingKey

pub fn from_bytes(bytes: &[u8; 57]) -> Result<Self, SignatureError>

Constructs a verifying key from a given byte slice.

Fails if bytes is not 57 bytes long, or if bytes does not represent a valid point on the curve.

pub fn raw_verify<CtxDigest>( &self, context: Option<&[u8]>, message: &[u8], signature: &Signature, ) -> Result<(), SignatureError>

where CtxDigest: Digest<OutputSize = U114>,

Verifies a given signature for a specified message.

As this function is intended to be internally used, please use VerifyingKey::verify instead unless you disable the “sha3” feature.

Trait Implementations

impl DigestVerifier<XofDigest<CoreWrapper<Shake256Core>, UInt<UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, B0>>, Signature> for VerifyingKey

fn verify_digest( &self, digest: Shake256U64, signature: &Signature, ) -> Result<(), SignatureError>

Verify the signature against the given [Digest] output.

impl TryFrom<&[u8]> for VerifyingKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl Verifier<Signature> for VerifyingKey

fn verify( &self, msg: &[u8], signature: &Signature, ) -> Result<(), SignatureError>

Use Self to verify that the provided signature for a given message bytestring is authentic.
