Specified by:

getAADStream in interface AADProcessor

Returns:

a stream for collecting associated data.

getDecryptingStream

public abstract CipherOutputStream getDecryptingStream(OutputStream out)

Description copied from interface: OutputDecryptor

Return a stream which will decrypt it's input writing the results to out.

Specified by:

getDecryptingStream in interface OutputDecryptor<T extends FipsParameters>

Specified by:

getDecryptingStream in class FipsOutputDecryptor<T extends FipsParameters>

Parameters:

out - the output stream to collect the decrypted data in.

Returns:

a stream for writing the encrypted data.

getMAC

public abstract byte[] getMAC()

Description copied from interface: AADProcessor

Return the final value of AEAD cipher's MAC.

Specified by:

getMAC in interface AADProcessor

Returns:

MAC value for the AEAD cipher.
