Expand description

A cryptographic signature generated by a private key.

Required Associated Types§

Source

type PrivateKey: PrivateKey

The private key type used to generate this signature.

Required Methods§

Source

fn sign(key: &Self::PrivateKey, message: &[u8]) -> Result<Self, Error>

Sign a message.

The input to this function is always a message, never a digest. If a signature scheme calls for hashing a message and signing the hash digest, sign is responsible for both hashing and signing.

Source

fn is_valid( &self, key: &<Self::PrivateKey as PrivateKey>::Public, message: &[u8], ) -> bool

Verify a signature.

The input to this function is always a message, never a digest. If a signature scheme calls for hashing a message and signing the hash digest, is_valid is responsible for both hashing and verifying the digest.
