Method Detail

signAfterUpdateRaw

byte[] signAfterUpdateRaw(boolean reset)

Parameters:

reset - - true to reset after the signature has been generated, false otherwise.

Returns:

the final signature generated for the processed data.

process

default byte[] process(byte[] input,
                       int offset,
                       int length,
                       boolean complete)

Description copied from interface: CryptoProcessor

Generic method to process and transform data.

CryptoProcessor	Equivalent of process(input, offset, length, complete)
HashCreator	update(input, offset, length); return hash(complete);
Cryptor	return crypt(input, offset, length, true);
SignatureSigner	update(input, offset, length); return signAfterUpdate(complete);
SignatureVerifier	throw new UnsupportedOperationException();

Specified by:

process in interface CryptoProcessor

Parameters:

input - the data to process.

offset - the index where to start reading data from input.

length - the number of bytes to read from input.

complete - - true to complete/reset this processor after processing the given input, false otherwise.

Returns:

the transformed input data.
