<p>Verify the certificate signature. </p>
<p>The verify callback is a user-supplied callback that can clear / modify / add flags for a certificate. If set, the verification callback is called for each certificate in the chain (from the trust-ca down to the presented crt). The parameters for the callback are: (void *parameter, <a class="el" href="structmbedtls__x509__crt.html" title="Container for an X.509 certificate. ">mbedtls_x509_crt</a> *crt, int certificate_depth, int *flags). With the flags representing current flags for that specific certificate and the certificate depth from the bottom (Peer cert depth = 0).</p>
<p>All flags left after returning from the callback are also returned to the application. The function should return 0 for anything (including invalid certificates) other than fatal error, as a non-zero return code immediately aborts the verification process. For fatal errors, a specific error code should be used (different from MBEDTLS_ERR_X509_CERT_VERIFY_FAILED which should not be returned at this point), or MBEDTLS_ERR_X509_FATAL_ERROR can be used if no better code is available.</p>
