                                           InvalidSignatureEncodingException

Decodes a signature.

The function a subclass would implement to finish decoding the key.

Parameters:

encodedSignature - A byte array containing the encoded signature.

signatureAlgorithm - A String representing the algorithm.

Returns:

The decoded signature.

Throws:

NoSuchAlgorithmException - Thrown if the specified algorithm cannot be found.

InvalidSignatureEncodingException - Thrown if the signature is formatted incorrectly.
