GNOME Crypto Ring FIPS 104-3 with wolfSSL

GNOME Crypto Ring (GCR) is a core library in the GNOME desktop environment. Built on libgcrypt, GCR can achieve FIPS 140-3 compliance using wolfSSL’s libgcrypt port. wolfSSL’s libgcrypt port ensures compliance for FIPS 140-3 in applications consuming GCR, such as: Certificate and Key Viewing: The gcr-viewer tool allows inspection of cryptographic files like X.509 certificates […]

Xilinx Accelerated Crypto with FIPS

It’s already possible to use ARMv8 crypto extensions with FIPS 140-3 using PAA (Processor Algorithm Acceleration) but did you know that we have researched using Xilinx/AMD’s hardened crypto with wolfSSL while being FIPS certified? Many benefits can come from using Xilinx/AMD’s hardened crypto accelerators, for example it free’s up the CPU to be used for […]

Updated Xilinx/AMD Versal Benchmarks

There are three build options for crypto operations when using wolfSSL on Xilinx/AMD Ultrascale+ devices. The lightweight wolfSSL library can use a software only implementation, make use of the ARMv8 crypto extensions along with custom ARM assembly, or offload the operation to the CSU. Each has its trade offs. Recently wolfSSL has made improvements to […]

wolfHSM DMA Feature Addition

wolfHSM provides a client-server model for interacting with HSM’s to do cryptographic operations and currently supports multiple transport mediums: TCP, POSIX shared memory (SHM), and DMA (direct memory access). It gives the option of using wolfCrypt with it’s FIPS 140-3 certification instead of a hardware HSM to take advantage of something like a secure trustzone. […]
