Method Detail

encryptStream

public OutputStream encryptStream(OutputStream outputStream)

Wraps the supplied OutputStream in a encrypted cipher stream, i.e. every plain text byte written into the new OutputStream is encrypted using our SecretKey.

Parameters:

outputStream - the plaint text output stream to encrypted

Returns:

a new OutputStream which will encrypt every byte written to it.

Parameters:

inputStream - the encrypted input stream

Returns:

new InputStream which will decrypt every byte read from it.
