sign method
Signs the provided digest using the appropriate algorithm based on the available signing key.
This method takes a digest as input and delegates the signing process to either the ED25519 or ECDSA algorithm based on the type of available signing key.
digest
The digest to be signed.
returns A list of bytes representing the generated signature using the appropriate algorithm.
Implementation
List<int> sign(List<int> digest) {
return _signEdward(digest);
}
