<p dir="auto">This replaces the uses of <code>safe_memcmp</code> with <code>gnutls_memcmp</code> which is resilient against timing attacks. Note that this doesn't imply that the previous code was vulnerable: they were either (1) both arguments are public or (2) both arguments are confidential (and thus the attacker is not able to leverage it for timing attacks unless it has access to the data already).</p>
<p dir="auto">Fixes #1042.</p>
