sign static method
Signs the payload with the keypair.
If the payload is greater than 256 bytes, it will be hashed with blake2b256 before signing.
Implementation
static Uint8List sign(KeyPair keyPair, Uint8List payload) {
if (payload.length > 256) {
payload = Hasher.blake2b256.hash(payload);
}
return keyPair.sign(payload);
}
