decodeSignature

protected DecodedSignature decodeSignature(ASN1InputByteArray parameters,
                                           byte[] encodedSignature,
                                           String algorithm,

                                           InvalidSignatureEncodingException

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

Parameters:

parameters - The parameters that specify the details of the encoding.

encodedSignature - A byte array containing the encoded signature.

algorithm - A String representing the name of the algorithm used to encode the data.

digestString - A String representing any parameters required by the signature decoder. Often this is a digest. Can be null.

Returns:

The decoded signature.

Throws:

NoSuchAlgorithmException - Thrown if the specified algorithm is invalid.

InvalidSignatureEncodingException - Thrown if the signature is improperly formatted or invalid.
