True Random vs. Pseudorandom Number Generation

In the world of computing, “randomness” isn’t a one-size-fits-all concept. Whether you are developing a gaming app or securing a high-stakes cryptographic protocol, the type of Random Number Generator (RNG) you choose matters. The distinction boils down to one factor: reproducibility. Download wolfSSL → Pseudorandom Number Generators (PRNGs) A PRNG is a deterministic algorithm. It […]

wolfIP 1.0.0 Released: Deterministic TCP/IP for Embedded and Safety-Critical Systems

We are excited to announce the release of wolfIP 1.0.0, the first public release of wolfSSL’s lightweight TCP/IP stack for embedded, real-time, and safety-critical systems. wolfIP is built around a simple idea: networking behavior should be defined before runtime, not discovered during it. With no dynamic memory allocation, fixed socket tables, pre-allocated packet buffers, and […]

wolfBoot adds DICE and Measured boot via PSA Initial Attestation

Secure boot establishes authenticity (“this image is signed by a trusted key”). But many modern deployments also need attestation: a portable, verifiable way to prove what actually booted to a relying party: during onboarding, after updates, and throughout a device’s lifetime. That’s where DICE (Device Identifier Composition Engine) comes in. DICE composes a device identity […]

TLS 1.3 Brainpool Curve Support in wolfSSL

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 […]

wolfSSL Inc. Announces wolfIP, a Tiny, Deterministic TCP/IP Stack for Embedded and Safety-Critical Systems

wolfIP is a deterministic TCP/IP stack designed for embedded and safety-critical systems where memory usage, timing, and behavior must be defined before runtime. By eliminating dynamic allocation and fixing system resources up front, it enables predictable operation that supports verification and certification efforts. Edmonds, Washington – April 7, 2026 – wolfSSL Inc. today announced wolfIP, […]
