At wolfSSL, we prioritize strong, modern cryptographic practices—especially for embedded systems where performance, code size, and reliability are critical. While TLS continues to be the standard for securing communications, many early protocol versions have been broken or deprecated due to serious security flaws. Understanding the history of these attacks and their mitigations helps clarify why […]

wolfCrypt Examples for Renesas RH850
The RH850 Family of 32-bit automotive microcontrollers (MCUs) is an automotive microcontroller equipped with an integrated Hardware Security Module (HSM). It ensures fast and secure key management, cryptographic processing, and authentication at the hardware level. Designed for next-generation ECUs, it combines functional safety with advanced security. wolfSSL has now provided a wolfCrypt use case on […]
Read MoreMore TagMD5 Disabled by Default in wolfSSL: What You Need to Know
As part of our ongoing effort to deliver secure-by-default cryptography, wolfSSL has disabled the MD5 hash algorithm by default in the latest release. Don’t worry, it isn’t going away completely, but just disabled at compile time, by default. Why Disable MD5? MD5 has been considered cryptographically broken for many years due to known collision attacks. […]

In the context of the recent collaboration between wolfSSL and Frontgrade Gaisler, we are excited to share some benchmark results of the wolfCrypt library running on the Gaisler GR740-MINI board. The GR740, designed as ESA’s Next Generation Microprocessor (NGMP), is a radiation-hardened System-on-Chip (SoC) featuring a quad-core fault-tolerant LEON4 SPARC V8 processor. WolfSSL and Gaisler […]
Read MoreMore TagBroken Cryptographic Algorithms
wolfSSL’s wolfcrypt library includes several cryptographic algorithms that are now considered broken or deprecated. While these algorithms are typically disabled by default, developers should be aware of their security implications. Here is the list of these algorithms along with links to documents explaining why they are no longer considered secure: RC4/ARC4: Prohibited for TLS use […]
