</p>

<div></div>

<p dir="auto">gnutls serv loads keyfile & cert, but doesn't bother to check if it should trust it or if it is acceptable as per policy.</p>

<p dir="auto">For example, one can start gnutls serv with 512 RSA keys in the cert chain, even if no sane client will trust to connect to it.</p>

<p dir="auto">Some checks are performed e.g. gnutls_check_key_cert_match, but it should also check if the cert meets the minimum profile security standard w.r.t. algos / key sizes / hashes / etc. Such that, for example, daemons fail to start with bogus certs instead of waiting for clients to fail to establish a connection.</p>
