As cryptographic standards and regulatory requirements continue to evolve, the ability to adopt modern security protocols without sacrificing compliance is increasingly important. TLS 1.3 plays a critical role in this evolution — not only as today’s baseline for secure communications but also as the foundation for the ongoing transition toward Post-Quantum Cryptography (PQC). With recent […]

Accelerating ML-DSA Key Generation with wolfSSL and CUDA
With the formalization of ML-DSA for post-quantum usage, lattice-based cryptography introduces a significant compute challenge. Unlike traditional ECC or RSA, ML-DSA relies on complex polynomial math across hundreds of dimensions, creating a performance wall for high-volume systems. To address this compute issue, wolfSSL can utilize CUDA to accelerate these lattice operations, offloading the heavy math […]

Read MoreMore TagwolfSSL and OpenTitan: Securing the Open Silicon Era
wolfSSL is initiating support for OpenTitan, the open-source silicon Root of Trust. Our implementation will integrate with OpenTitan’s hardware accelerators, specifically the OpenTitan Big Number (OTBN) unit, AES, and HMAC/KMAC blocks, to offload cryptographic operations from the host RISC-V core. This integration provides a transparent, FIPS-ready security stack for embedded designs. The programmable OTBN unit […]
Read MoreMore TagNXP S32K1 CSE Hardware Acceleration supported by wolfSSL
wolfSSL now supports using the Cryptographic Services Engine (CSE) on NXP S32K1 microcontrollers for hardware-accelerated cryptography. The CSE is a secure coprocessor integrated into automotive-grade microcontrollers like the S32K148, providing AES acceleration, hardware TRNG, and secure key storage. The port uses wolfSSL’s Crypto Callback mechanism, so when operations aren’t supported by CSE hardware (like AES-192/256), […]

Read MoreMore TagwolfSSL adds support for libspdm 3.7.0
wolfSSL now includes updated support for libspdm 3.7.0. libspdm is the reference implementation of the DMTF’s Security Protocols and Data Models (SPDM) specifications, which provide device attestation, authentication, and mechanisms for establishing secure communications over any transport. Both wolfSSL and SPDM are designed to be transport-agnostic, making them a good fit together. Download wolfSSL → […]
