Description copied from class: SignatureDecoder
Decodes the input stream.

Specified by:
decodeSignature in class SignatureDecoder
Parameters:
encodedSignature - An input stream containing the encoding.
signatureAlgorithm - The signature algorithm used.
Returns:
A DecodedSignature object from which a signature verifier can be obtained.
Throws:
NoSuchAlgorithmException - Thrown if the specified encoding algorithm cannot be found.
InvalidSignatureEncodingException - Thrown if the signature is incorrectly formatted.
