Function amqp_ssl_validate_hostname


#include <librabbitmq/amqp_openssl_hostname_validation.h>

amqp_hostname_validation_result amqp_ssl_validate_hostname(const char *hostname, const X509 *server_cert)


Validates the server's identity by looking for the expected hostname in the server's certificate. As described in RFC 6125, it first tries to find a match in the Subject Alternative Name extension. If the extension is not present in the certificate, it checks the Common Name instead.

Returns AMQP_HVR_MATCH_FOUND if a match was found. Returns AMQP_HVR_MATCH_NOT_FOUND if no matches were found. Returns AMQP_HVR_MALFORMED_CERTIFICATE if any of the hostnames had a NUL character embedded in it. Returns AMQP_HVR_ERROR if there was an error.
