Struct VerifyingKey 

pub struct VerifyingKey(/* private fields */);

An Ed25519 verifying key: a compressed edwards25519 point, 32 bytes.

Parsing does not validate the point; the driver does, when the key is used, and reports Error::InvalidKey.

Implementations

impl VerifyingKey

pub fn from_bytes(bytes: &[u8; 32]) -> Self

Load a verifying key.

pub fn to_bytes(&self) -> [u8; 32]

The verifying key bytes.

pub fn as_bytes(&self) -> &[u8; 32]

The verifying key bytes.

pub fn as_driver(&self) -> &Ed25519PublicKey

The driver representation.

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

Verify the signature of a message.

Fails with Error::InvalidSignature if the signature does not verify, or with Error::InvalidKey if this key does not decode to a point on the curve.
