      org.apache.tapestry5.internal.util.MacOutputStream

All Implemented Interfaces:

Closeable, Flushable

public class MacOutputStream
extends OutputStream

An output stream that wraps around a Mac (message authentication code algorithm). This is currently used for symmetric (private) keys, but in theory could be used with assymetric (public/private) keys.

Since:

5.3.6

Constructor Summary

MacOutputStream(Mac mac)

Method Summary

String	getResult() Should only be invoked once, immediately after this stream is closed; it generates the final MAC result, and returns it as a Base64 encoded string.
static MacOutputStream	streamFor(Key key)
void	write(byte[] b)
void	write(byte[] b, int off, int len)
void	write(int b)
