Last year, we wrote about the support we added for the Raspberry Pi Pico in wolfSSL. Since then, we haven’t been sitting idle. The wolf pack has been busy adding even more security goodness to the Pico ecosystem. If you thought TLS on a $1 microcontroller was impressive, wait until you see what we’ve been […]

RSA-PSS Support for PKCS#7 SignedData in wolfSSL
PKCS#7, standardized as Cryptographic Message Syntax (CMS) in RFC 5652, is a common format for signing structured data. Signed firmware updates, signed configuration packages, and certificate-based authentication workflows all rely on PKCS#7 SignedData to ensure integrity and authenticity.wolfSSL now supports RSA-PSS (RSASSA-PSS) signatures in PKCS#7 SignedData, for both generation and verification. This lets applications move […]
Read MoreMore TagExpanded AIA Support in wolfSSL
We recently added new functionality that improves how wolfSSL handles Authority Information Access (AIA) certificate data. AIA is an X.509 certificate extension that tells clients where to find related validation resources, typically OCSP responder URLs (for revocation status checks) and CA Issuers URLs (for downloading issuer certificates), defined in RFC 4325. In practice, this helps […]

The Embedded Redfish Server packages the Barracuda Web Server for rapid development of secure Redfish services on embedded devices. Cryptographic services are provided by wolfSSL, a compact TLS/SSL library optimized for embedded systems, with security functions implemented using wolfCrypt and FIPS 140-3 validated cryptography. Getting started with wolfSSL? Download the latest libraries here and start […]
Read MoreMore TagPerformance and Portability: Post-Quantum Cryptography with wolfSSL and Vulkan
Post-quantum standards like ML-DSA introduce significant compute challenges. These lattice-based schemes rely on high-degree polynomial math that can overwhelm traditional CPUs, making GPU acceleration essential for high-volume environments. The primary bottlenecks occur during Key Generation and Signing. In ML-DSA, signature generation is particularly intensive due to rejection sampling. This process requires the algorithm to repeatedly […]
Read MoreMore TagIdiomatic Zig Bindings for wolfSSL
wolfSSL now has a community-maintained Zig binding—zig-wolfssl—that wraps wolfSSL and wolfCrypt behind a native Zig API. If you are building a Zig application that needs TLS, X.509, or wolfCrypt algorithms, this binding gives you type-safe access without dropping to raw C. New to Zig? Check out the official overview or visit ziglang.org. Getting started with […]
