@Suspendable abstract fun sign(bytes: ByteArray, publicKey: PublicKey): WithKey
Using the provided signing PublicKey internally looks up the matching PrivateKey and signs the data.
bytes - The data to sign over using the chosen key.
publicKey - The PublicKey partner to an internally held PrivateKey, either derived from the node's primary identity,
or previously generated via the freshKey method.
If the PublicKey is actually a CompositeKey the first leaf signing key hosted by the node is used.
IllegalArgumentException - if the input key is not a member of keys.
@Suspendable abstract fun sign(signableData: SignableData, publicKey: PublicKey): TransactionSignature
Using the provided signing PublicKey internally looks up the matching PrivateKey and signs the SignableData.
signableData - a wrapper over transaction id (Merkle root) and signature metadata.
publicKey - The PublicKey partner to an internally held PrivateKey, either derived from the node's primary identity,
or previously generated via the freshKey method.
If the PublicKey is actually a CompositeKey the first leaf signing key hosted by the node is used.
IllegalArgumentException - if the input key is not a member of keys.
