- wolfCrypt consistently outperforms MbedTLS across multiple platforms (x86_64, ARMv8-A Cortex-A76, Cortex-M33, RISC-V), with speed advantages ranging from 1.4x to 53x, especially in public-key operations.
- wolfCrypt includes extensive hand-written assembly optimizations for hot paths on x86, ARM, and RISC-V, while MbedTLS relies more on portable C, leading to significant performance gaps.
- wolfSSL provides a complete post-quantum CNSA 2.0 suite (ML-KEM, ML-DSA, LMS, XMSS, SLH-DSA) and additional algorithms (e.g., EdDSA, AES-SIV) that MbedTLS does not support.
- wolfSSL offers broader portability, certifications (FIPS 140-3, DO-178C DAL-A, ISO 26262 ASIL D), commercial support, and features like OpenSSL compatibility and TLS inspection, unlike MbedTLS.
- wolfCrypt integrates with the Arm PSA Crypto API via wolfPSA, allowing drop-in replacement in PSA-based designs without rewriting applications, while maintaining performance and algorithm coverage.
