Idiomatic 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 […]
Read MoreMore TagDid you know that you can run an fTPM in ARM TrustZone?
wolfTPM now has an integrated fTPM (firmware TPM) implementation built for the purpose of running within TrustZone for maximizing security! Why run an fTPM? Late breaking requirements come in to add a TPM to the design, but you didn’t include a hardware TPM on your board. You ship in high volumes and want TPM quality […]

Read MoreMore TagHow to Get CRA-Ready: Secure Devices and Simplify Compliance
The EU Cyber Resilience Act (CRA) is about to reshape how every connected device is designed, secured, and maintained. As the CRA introduces new expectations for secure development and long-term product protection, teams need a clear understanding of what will change and how to prepare. In this webinar on April 30 at 8 AM PT, […]
Read MoreMore TagGuidance for FIPS Customers: Auditing Direct Calls to wc_ecc_verify_hash()
The fix for CVE-2026-5194 is available in wolfSSL 5.9.1. Upgrading to the new version resolves the issue for TLS, DTLS, and X.509 users. FIPS customers need to take a closer look. FIPS users who call wc_ecc_verify_hash() or wc_ecc_verify_hash_ex() directly may remain exposed until they add a small check at their call sites. The required check […]
Read MoreMore TagFortifying Mission-Critical Systems: Where Cybersecurity Meets Radiation Protection
Secure boot in space isn’t just about signing firmware. It has to survive radiation faults, long-mission lifecycles and limited update windows. Join VORAGO Technologies and wolfSSL on April 29 at 9 AM PT for a technical session on implementing secure boot in real satellite environments. In orbit, your hardware and software are under constant assault. […]
Read MoreMore TagWhy C Remains the Gold Standard for Cryptographic Software
Executive Summary For production cryptographic software, memory safety alone does not define security. Real-world crypto must run on every platform, maintain stable assumptions over decades, and allow explicit control over hardware behavior. While memory-safe languages like Rust offer real benefits, serious cryptographic implementations inevitably rely on unsafe code, assembly, and low-level control, eroding those guarantees. […]
