<p dir="auto">You are right, i have made the mistake with using the <code>aead</code> instead of <code>cipher</code> here.</p>
<p dir="auto">Regarding <code>..update_last()</code> would it be sufficient to check the size of the message and call it only when it differs from the block size as GnuTLS doesn't indicate last message (as of my knowledge)</p>
