Introducing tinytls13: A minimal TLS 1.3 build profile that fits a complete client in about 30 KB of flash.
In brief. tinytls13 is a new wolfSSL build profile for deeply constrained devices. It compiles a complete, working TLS 1.3 client in about 30.8 KB of flash on an ARM Cortex-M33, with no X.509 and no extras you did not ask for. Why we built it Secure boot, attestation, and IoT connectivity increasingly need TLS […]

wolfSSL is proud to announce that active development has started to support offloading cryptographic operations to the ASU subsystem found on the Xilinx Versal Gen 2. We are currently implementing offload support for TRNG, SHA2, SHA3, SHAKE, HMAC, AES, RSA, and ECC. This will help enable future wolfSSL projects on the Versal Gen 2 platform, […]

By now, anyone who tracks security protocols has heard ad nauseum about the White House Executive Order 14412 regarding post-quantum cryptography (PQC). In case you’ve been hiding under a rock, it can be found here. The TL;DR is that all High Value Assets (HVAs) must use PQC key establishment by 2030 and PQC digital signatures […]
Read MoreMore TagPreliminary MACsec Key Agreement (MKA) Support, Built for AUTOSAR
Secure in-vehicle and industrial Ethernet is moving from “nice to have” to “required,” and MACsec (IEEE 802.1AE) is at the center of it — providing line-rate Layer 2 encryption, integrity, and replay protection directly on the wire. But MACsec doesn’t key itself. It needs a control plane to discover peers, prove liveness, elect a Key […]

Read MoreMore TagwolfSSL vs MbedTLS – An apples-to-apples benchmark across Intel, ARM (Cortex-A and Cortex-M), and RISC-V targets.
Scope: the full wolfCrypt algorithm suite vs MbedTLS, measured the same way on four platforms (Intel x86_64, a Raspberry Pi 5 (ARMv8-A Cortex-A76), a bare-metal STM32H563 Cortex-M33, and a Microchip PolarFire SoC RISC-V U54), plus the post-quantum and extended-algorithm coverage MbedTLS does not have. wolfSSL v5.9.1, MbedTLS 3.6.6, June 2026. Method: identical sources built from […]
Read MoreMore TagMaintaining FIPS Validation: Shifting from BitLocker to VeraCrypt with wolfCrypt
In September of 2026, the Cryptographic Module Validation Program (CMVP) will move all remaining FIPS 140-2 certificates to the Historical List, including the modules powering Windows BitLocker. For organizations navigating FIPS, CMMC, and FedRAMP, this is an immediate critical stop, as NIST guidance states federal agencies “should not include” Historical-status modules in new procurements, and […]
Read MoreMore TagwolfKeyMgr: Decrypt Internal TLS 1.3 Traffic Without Breaking It
TLS 1.3 made per-session forward secrecy the default. That is a win for privacy on the open internet, but inside your own data center it leaves monitoring, compliance, and intrusion-detection tools blind to the traffic they are meant to watch. wolfKeyMgr is wolfSSL’s answer. What wolfKeyMgr Does wolfKeyMgr is a secure key management service […]
Read MoreMore TagWhy is wolfSSL reporting so many CVEs?
Why are we reporting so many CVEs? If you follow wolfSSL, you’ve probably noticed the number of CVEs we file per release has ramped up this spring 2026. From 5.8.0 (April 2025) to 5.9.1 (April 2026) we’ve experienced nearly geometric growth in reported CVEs per wolfSSL release. So what’s going on? Should users of wolfSSL […]
