Hi! As our readers know, wolfSSL produces the first embedded TLS library that has begun testing for the new FIPS 140-3 standard, as listed here: https://csrc.nist.gov/projects/cryptographic-module-validation-program/modules-in-process/iut-list
One of the things that is critical to our users is Key Derivation Functions, which are explained here: https://en.wikipedia.org/wiki/Key_derivation_function
Key derivation functions are consumed by TLS 1.2, TLS 1.3, and SSH. We will support KDF’s for all three in our new FIPS 140-3 certificate.
If you have questions on FIPS 140-3 or our progress on the effort, please contact us at facts at wolfssl .com or give us a call.
