wolfCrypt Is Quantum-Safe and has a FIPS 140-3 CAVP cert!
We’re proud to announce that wolfCrypt Post Quantum has officially received CAVP validation from NIST, listed under certificate #A8437. This validation covers the CNSA 2.0 compatible algorithm library contained within the wolfSSL TLS bundle (v7.0.0), and is a critical milestone on the path to a full FIPS 140-3 module validation for our post-quantum module. Certificate […]

The LAUNCHXL-F28P55X (TMS320F28P550SJ) features a 150 MHz C28x DSP from TI’s C2000 real-time control family. Designed for motor drives, solar inverters, EV chargers, and digital power supplies, it lacks a hardware TRNG. However, it provides three independent clock sources: two on-chip RC oscillators (INTOSC1 and INTOSC2) and the crystal driving the PLL. Using the chip’s […]
Read MoreMore TagwolfCOSE Adds PSA Attestation and EAT Support
wolfSSL is adding PSA Initial Attestation API 2.0 and RFC 9783 PSA Entity Attestation Token (EAT) support to wolfCOSE. This lets a device prove its identity, security lifecycle state, and boot measurements to a relying party using the compact COSE/CBOR formats already used across the IoT ecosystem. Consistent with wolfCOSE’s design, PSA/EAT is fully off […]
Read MoreMore TagHardware AES for wolfCrypt on the TI C2000 C28x
The TI C2000 family is TI’s real-time control line: the MCUs inside motor drives, solar inverters, EV chargers and digital power supplies. wolfCrypt now drives the hardware AES accelerator on the LAUNCHXL-F28P55X (TMS320F28P550SJ), a 150 MHz C28x DSP with 133 KB RAM and 1088 KB flash. The F28P550SJ carries an on-chip AESA block, a TI […]
Read MoreMore TagwolfCOSE Adds COSE Countersignatures
wolfSSL is adding RFC 9338 COSE Countersignature support to wolfCOSE, letting a second party sign over an already-signed, encrypted, or MAC’d COSE message. Countersignatures matter for notarization, timestamping, and multi-party workflows, proving that a message existed and was endorsed by an additional authority after the fact, and making wolfCOSE a fit for supply-chain and attestation […]
Read MoreMore TagWhat We’ve Been Building: A wolfMQTT Update
Since the wolfMQTT 2.1.0 release back in July, the team has been busy working on some major upgrades. Whether you’re running a client or a broker, there’s a lot to dig into in the current master branch on GitHub. We’ve focused on smoothing out the developer experience, tightening up protocol compliance, and, most importantly, a […]
Read MoreMore TagBringing wolfSSL in line with RFC 9846
RFC 9846, published in July 2026, obsoletes RFC 8446 as the specification for TLS 1.3. It is a minor revision in that it is backward compatible, but it tightens a number of requirements that were previously advisory. At wolfSSL, we are working hard on implementing the specification. No KeyUpdate while sending early data. Section 5.5 […]
Read MoreMore TagOpenBao FIPS 140-3 Support with wolfProvider
OpenBao is an open-source secrets management platform used to store, manage, and distribute credentials, encryption keys, and certificates. wolfSSL is evaluating OpenBao with wolfProvider to verify operation with wolfCrypt FIPS. OpenBao can use FIPS 140-3 validated cryptography through wolfProvider with no code changes to OpenBao and potentially no code changes to applications using it, provided […]
Read MoreMore TagwolfBoot now supports booting FAT32 and ext4 Filesystems
wolfBoot can now read a signed firmware image from a file on a filesystem. This applies to the disk boot path, which covers SD cards, eMMC, SATA and NVMe targets. The feature is read only, optional, and off by default. What it does wolfBoot has supported MBR and GPT partition tables on disk targets for […]
Read MoreMore TagwolfSSL Advances Embedded Security with wolfIP, New Post-Quantum Capabilities and AURIX™ TC4xx Support
wolfSSL announced three advances for embedded systems: the deterministic wolfIP TCP/IP stack, broader post-quantum support spanning NIST-validated algorithms and native Falcon and FrodoKEM implementations, and wolfHSM support for the Infineon AURIX™ TC4xx. Together, these capabilities support predictable networking, the transition to post-quantum cryptography, and isolated cryptographic services for automotive systems. EDMONDS, Wash., Sept. 21, 2026 […]
