Description copied from interface:TlsSigner
Generate an encoded signature based on the passed in hash.- Parameters:
algorithm
- the signature algorithm to use.hash
- the hash calculated for the signature.- Returns:
- an encoded signature.
- Throws:
java.io.IOException
- in case of an exception processing the hash.
