Overview
x509_plus is a Dart library designed for parsing and manipulating X.509 certificates, enabling secure handling of digital certificates in applications. It supports reading certificate data from various formats, extracting key information such as subject, issuer, validity periods, and public keys, and validating certificate chains. The library is particularly useful in scenarios requiring secure authentication, TLS configuration, or certificate inspection. Built with cross-platform compatibility in mind, it works seamlessly across Android, iOS, Web, macOS, Windows, and Linux.
