Securing the Web: Rustls on track to outperform OpenSSL Prossimo is funding the development of Rustls, a high-quality TLS implementation written in Rust, with the aim of replacing less safe alternatives such as OpenSSL. This article goes into recent developments in performance tracking for Rustls and provides a performance comparison between Rustls 0.22.0 and OpenSSL 3.2.0 - the latest releases of both projects at the time of writing. Our investment in benchmarking has helped confirm that Rustls is competitive with OpenSSL.
