      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:
      IOException - in case of an exception processing the hash.
