protected void writeHeader(java.io.OutputStream q)
                    throws java.io.IOException

Description copied from class: AbstractBlockCipherOutputStream

Write the first part of the "header", not including any required stream length information. For CBC ciphers, this is usually just the IV. NB. You should wash the header through your MAC. The CCSBlockCipher's buffer is available as scratch space.

Specified by:

writeHeader in class AbstractBlockCipherOutputStream

Parameters:

q - The stream to write to.

Throws:

java.io.IOException
