Crate readme

Short description webpki is a library that validates Web PKI (TLS/SSL) certificates.

Long description webpki is used by Rustls to handle certificate-related tasks required for implementing TLS clients and servers. Written in Rust, it uses 'ring' for cryptographic operations and low-level parsing. This is a fork of the original webpki project, released as the rustls-webpki crate, beginning with version 0.100.0.

Features • Representing trust anchors - requires caller to specify a set of trust anchors using the TrustAnchor type. • Parsing certificates - converts from raw encoded form of a certificate for trust decisions. • Path building - determines if a certificate was issued by a trust anchor or intermediates endorsed by it. • Name/usage validation - checks if a certificate is valid for a given DNS name or IP address.
