wolfSSL Rust Wrapper coming soon
Rust support is coming to wolfSSL this year! The wolfSSL embedded TLS library is a lightweight, portable, C-language-based SSL/TLS library known for its low footprint, speed, and feature set. Users have been able to take advantage of our library not only in C but also in their Java, C#, Python, and JavaScript projects using the […]
Read MoreMore TagwolfSSL Support for the Espressif ESP-IDF v5.2 Beta
Recently Espressif announced their ESP-IDF v5.2 Beta 1 on GitHub. The same day we found out about this exciting new version, we confirmed that all the wolfSSL Espressif ESP32 Examples are working in that environment. So far the “beta” looks to be well polished from our perspective. Last week, we learned about the ESP-IDF v5.2 […]

Read MoreMore TagwolfSSL on Pi5 Benchmarks
We at wolfSSL have worked hard to provide exceptional performance for our libraries across all platforms, but we’ve taken extra measures for Intel, ARM, RISC-V and PPC. For common key sizes and curves we’ve implemented inline assembly speedups for most algorithms. For example on the new Raspberry Pi5 with a Cortex A57 at 2.4GHz (default) […]
Read MoreMore TagThumb2 Gets Assembly Code for AES and SHA-2 Algorithms in WolfSSL 5.6.4
In an effort to improve our Thumb2 support for Cortex-M4 and the like, wolfSSL 5.6.4 includes assembly code for the AES-ECB/CBC/CTR/GCM, SHA-256 and SHA-512 algorithms. Of particular interest is the AES-CBC and AES-GCM performance improvements you will see when changing from the C code implementations in wolfSSL 5.6.3. Take for example running wolfSSL on a […]
Read MoreMore TagThumb2 and Arm32 Public Key Gets Massive Speedup in wolfSSL 5.6.4
In the latest release of wolfSSL, version 5.6.4, a significant effort has been put into improving the performance of public key algorithms for 32-bit ARM chips. wolfSSL now has arguably the best performance for P256 ECC, Curve25519 and Ed25519 for Cortex-M4 and Cortex-A32. With highly optimized assembly implementations of multiplication and squaring operations you now […]
