Read MoreMore TagDirect Entropy Injection in ML-KEM: Understanding MakeKeyWithRandom and DRBG Bypass
At Crypta Labs, we are interested in direct applications of quantum random number generators (QRNG). This interest led us to explore how we can use our QRNG entropy directly in cryptographic operations, without intermediate processing layers. As we transition to post-quantum cryptography (PQC), it’s important to understand the need for randomness in these new algorithms. […]

Read MoreMore TagEnhancing wolfSSL’s Security with Fil-C: Finding Buffer Bugs Before They Bite
At wolfSSL, we’re constantly looking for ways to improve the security and reliability of our cryptographic library. Recently, we integrated the Fil-C compiler into our continuous integration (CI) pipeline, and it’s already paying dividends. Within the first runs, Fil-C caught a subtle but important buffer size validation bug that could have led to buffer overflows […]

The wolfSSL team is pleased to announce the release of wolfBoot 2.7.0, the latest version of our portable secure bootloader for embedded systems. This release focuses on three main areas: Expanding hardware coverage to radiation-hardened platforms Unifying and hardening TrustZone-M and dual-bank update flows Making update state tracking and integration easier with filesystem and MTD-backed […]
Read MoreMore TagwolfHSM Image Manager
wolfSSL is pleased to introduce the wolfHSM Image Manager, a new module for authenticated firmware verification in automotive and industrial systems. It provides a flexible, callback-based architecture for cryptographically verifying firmware before execution, complementing wolfBoot to form a secure chain of trust anchored in HSM hardware. Features Hardware-backed verification: All cryptographic operations use HSM-protected keys […]
Read MoreMore TagwolfBoot Training – Master Secure Boot on Embedded Systems
Secure boot is the foundation of firmware trust in embedded systems. It ensures that only authenticated, cryptographically verified firmware executes at startup — protecting devices from tampering, supply-chain attacks, and unauthorized updates. Join us on December 17 at 9 AM PT for a hands-on session that teaches you how to configure, build, and port wolfBoot, […]
