Introduction to wolfCert: Certificate Enrollment for Embedded Devices
Device certificates need renewal. Keys need rollover. Across an embedded fleet, both must work within tight memory and processing limits. Join wolfSSL for an introduction to wolfCert, the successor to wolfSCEP. Learn how to integrate certificate enrollment into MCU and RTOS applications within your device’s resource limits. This webinar will cover: EST and SCEP: differences […]
Read MoreMore TagwolfBoot Secure Boot on the NXP i.MX 8QuadMax
wolfBoot now runs on the NXP i.MX 8QuadMax MEK as BL33, taking the place of U-Boot inside the NXP boot container. The i.MX 8QuadMax is used in automotive, industrial and medical designs, where the boot chain often has to be auditable, and this puts a small bootloader that checks a signature in the last position […]
Read MoreMore TagwolfSSL on the Silicon Labs EFR32 Secure Element
wolfSSL now offloads cryptography to the Silicon Labs EFR32 Series 2 Secure Element through wolfCrypt crypto callbacks. Define WOLFSSL_SILABS_CRYPTOCB, and your application code does not change. This covers wolfCrypt and TLS together. Because operations route by device id rather than by a compile time hook, the same offload serves a direct wolfCrypt API call and […]
Read MoreMore TagwolfSSL Wins Two 2026 Best in Show Awards for wolfHSM and wolfIP
Two wolfSSL products have been recognized for their contributions to embedded systems. wolfHSM won a Best in Show award at GVSETS, and wolfIP won a Best in Show award at embedded world North America. wolfHSM Automotive Hardware Security Modules wolfHSM is a portable HSM solution for automotive and embedded systems. Its client-server architecture moves sensitive […]
Read MoreMore TagHardware Crypto for the Nuvoton NuMicro M2354
wolfSSL now runs its cryptography on the hardware accelerators of the Nuvoton NuMicro M2354, an Arm Cortex-M23 microcontroller with TrustZone. Hashing, AES, RSA, and elliptic curve operations move off the CPU and onto the chip’s CRPT engine. Offloads SHA-1 through SHA-512, AES in ECB, CBC and CTR modes, AES-GCM and AES-CCM authenticated encryption, RSA, ECDSA […]
Read MoreMore TagwolfBoot SD Card support for NXP LS1028A
wolfBoot now boots a signed application from an SD card on the NXP LS1028A, so the boot image lives on removable storage instead of NOR flash. Booting from the card Loads the signed image over the on chip eSDHC controller and verifies it before handing over control. Uses A/B partitions on a GPT or MBR […]
Read MoreMore TagwolfSSL supports the S32K3 ACE Accelerator
wolfSSL now supports offloading AES-ECB and AES-CMAC operations on S32K3 family devices equipped with the ACE accelerator. This accelerator is featured specifically on the S32K388 and S32K389. The ACE accelerator provides a significant speedup compared to our software implementation and the native HSE operations available on the S32K3. This means you can keep your keys […]
Read MoreMore TagwolfCOSE Adds COSE HPKE Encryption
wolfSSL is adding Hybrid Public Key Encryption (HPKE) support to wolfCOSE. HPKE, standardized in RFC 9180, combines a KEM, a KDF, and an AEAD into a modern, misuse-resistant public-key encryption scheme, and bringing it to COSE lets constrained and IoT devices encrypt CBOR-based messages to one or many recipients without hand-rolled key wrapping. The feature […]
Read MoreMore TagThe wolfMQTT Broker: Persistence, Encryption at Rest, and a Round of Hardening
For ten years, wolfMQTT operated purely as a client library. With v2.0.0, we introduced its counterpart: a lightweight MQTT broker built on the same codebase, maintaining our strict footprint requirements and TLS stack. Over the last two releases, we’ve added core features needed to survive process restarts, along with fixes for edge cases that surface […]
Read MoreMore TagwolfCOSE Adds Post-Quantum LMS Signatures
wolfSSL is adding RFC 8778 HSS/LMS stateful hash-based signature support to wolfCOSE, giving COSE a NIST-approved, quantum-resistant signing option today. Hash-based signatures are attractive for firmware and long-lived attestation because their security rests only on the hash function, and bringing LMS to COSE lets customers adopt post-quantum signing inside the compact CBOR message formats they […]
