With Go's crypto/x509 package, developers frequently run into issues with important additions such as X509v3 Policy Constraints. When employing intermediate certificates with stringent regulations, these problems can interfere with certificate chain validation. It is feasible to overcome these obstacles and keep safe systems by putting in place customized solutions, including customized verifiers.

It can be difficult to parse X.509 certificates in Go when working with non-compliant fields, such as the Subject's prohibited characters. Alternative tools such as OpenSSL provide greater flexibility, but Go's stringent crypto library enforces standards. Practical solutions include custom parsers or external tools to handle real-world certificate issues efficiently.
