For the past eight months, Trail of Bits has worked with the Python Cryptographic Authority to build cryptography-x509-verification, a brand-new, pure-Rust implementation of the X.509 path validation algorithm that TLS and other encryption and authentication protocols are built on. Our implementation is fast, standards-conforming, and memory-safe, giving the Python ecosystem a modern alternative to OpenSSL’s misuse- and vulnerability-prone X.509 APIs for HTTPS certificate verification, among other protocols. This is a foundational security improvement that will benefit …
