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 […]

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), […]

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 → […]

wolfSSL in the kernel The last year has been quite active for wolfSSL in kernel space. To give a quick recap, we’ve added support to register wolfCrypt algs in the Linux kernel crypto API (making them available for filesystem encryption, IPsec, etc) wrote patches for Linux /dev/random, giving it FIPS-compliant wolfCrypt implementations introduced wolfGuard, a […]

At wolfSSL, we continuously work to keep our TLS and cryptography engine fast, portable, secure, and lightweight. Most improvements come in the form of new features, optimizations, or platform ports. But sometimes the most valuable contributions are the ones that simplify the code rather than expand it. A recent community contribution highlighted exactly this. Pull […]

wolfSSL 5.8.4 (PR#9309) has expanded the crypto callback api to include support for copy and free operations. This addition addresses a lifecycle management challenge for developers integrating hardware security modules (HSM) or hardware accelerators. Download wolfSSL → The Capability Previously, wolfSSL’s default behavior for duplicating a hash context was a standard memory copy. While efficient […]
