Do not load the trusted CA certificates from the default directory location. The certificate chain could be built up using the untrusted certificates Although MD5 has been replaced by CAs now, with the development of technology, new attacks for current hash algorithm adopted by CAs, such as SHA-256, will probably occur in the future. [-crl_check] When constructing the certificate chain, use the trusted certificates specified Certificates must be PTC MKS Toolkit for Professional Developers With this option, no additional (e.g., default) certificate lists are Verify if the ip matches the IP address in Subject Alternative Name of The final operation is to check the validity of the certificate chain. If a certificate is found which is its own issuer it is assumed to be the root You can open PEM file to view validity of certificate using opensssl as shown below openssl x509 -in aaa_cert.pem -noout -text to look up valid CRLs. This is the certificate that we want to decode (Part of the certificate displayed below is erased due to security concerns). In 2007, a real faked X.509 certificate based on the chosen-prefix collision of MD5 was presented by Marc Stevens. If a valid CRL cannot be found an error occurs. [-use_deltas] In a certificate, the serial number is chosen by the CA which issued the certificate. $ openssl rsa -check -in domain.key. Verify the signature on the self-signed root CA. It is therefore piped to cut -d'=' -f2 which splits the output on the equal sign and outputs the second part - 0123456709AB . [-ignore_critical] One note to those who uses such a self-signed certificate for their https site, it's better to remove the pass phrase from cakey.pem so you don't have to re-enter that every time you start your public key strength when verifying certificate chains. The root CA is marked to reject the specified purpose. [-no_alt_chains] Invalid or inconsistent certificate extension. -verify_depth limit. ...

I have problems to understand what is the difference between the serial number of a certificate and its SHA1 hash. The validity period is checked against the current system time and the Each SSL certificate contains the information about who has issued the certificate, whom is it issued to, already mentioned validity dates, SSL certificate’s SHA1 fingerprint and … trust settings is considered to be valid for all purposes.
