decodeSignature in class SignatureDecoderencodedSignature - An input stream containing the encoded signature
data.signatureAlgorithm - A String representing the signature algorithm.
NoSuchAlgorithmException - Thrown if the specified algorithm is
invalid.
InvalidSignatureEncodingException - Thrown if the encoded signature
is improperly formatted.
