Just look at SSL_CTX_set_verify() documentation on callback function
for example from:
The return value of verify_callback controls the strategy of the further
verification process. If verify_callback returns 0, the verification
process is immediately stopped with ``verification failed' state. If
SSL_VERIFY_PEER is set, a verification failure alert is sent to the peer
and the TLS/SSL handshake is terminated. If verify_callback returns 1,
the verification process is continued. If verify_callback always returns
1, the TLS/SSL handshake will not be terminated with respect to
verification failures and the connection will be established. The
calling process can however retrieve the error code of the last
verification error using SSL_get_verify_result(3) or by maintaining its
own error storage managed by verify_callback.

Ssl_ctx_set_verify Locations

  • SSLCTXsetverify(k-ctx, SSLVERIFYPEER, krxsslverifypeer); The comment added seems to be not correct. SSLVERIFYPEER does request client to send certs to server to authenticate client at server.
  • Sildenafil indian brands SSLCTXsetverify sets the verification flags for ctx to be mode and specifies the verifycallback function to be used. If no callback function shall be specified, the NULL pointer can be used for verifycallback.
  • The latter is set using the SSLCTXsetverify(3) family of functions. Providing a complete verification procedure including certificate purpose settings etc is a complex task. The built-in procedure is quite powerful and in most cases it should be sufficient to modify its behaviour using the verifycallback function.
