com.icodici.crypto.SymmetricKey.EtaEncryptingStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

Enclosing class:

SymmetricKey

public class SymmetricKey.EtaEncryptingStream
extends java.io.OutputStream

Encrypts an AE (EtA) stream using Sha256-based HMAC. When all the data are written, call end() or close() explicitely to add HMAC record. The difference is, close() closes the output stream too.

Method Summary

Method Detail

end

public void end()
         throws java.io.IOException

Finishes encryption and writes down HMAC record. Futhher writing will cause EOFException. Does not close the underlying output stream!

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Calls end(), if wasn't called before, and closes undelying stream. Therefore, it is not possible to use the undelying stream after calling it.
