fn derive_public_key(
    &mut self,
    secret_key: SecretKey
) -> Result<Vec<u8>, Self::Error>

Function to derive public key given a secret key.

Arguments

  • secret_key - The secret key to derive the public key

Returns

  • If successful, a vector of bytes with the public key

fn sign(
    &mut self,
    secret_key: SecretKey,
    message: &[u8]
) -> Result<Vec<u8>, Self::Error>

Arguments

  • message - The message to be signed
  • secret_key - The secret key for signing

Returns

  • If successful, a vector of bytes with the signature

fn verify(
    &mut self,
    signature: Signature,
    message: &[u8],
    public_key: PublicKey
) -> Result<(), Self::Error>
