Improved OCSP Support in wolfSSL

wolfSSL has recently made important improvements to its Online Certificate Status Protocol (OCSP) support. A recent fix in pull request #7779 addresses an issue where the OCSP request was incorrectly freed when saved in ssl->ctx->certOcspRequest. This update ensures that the OCSP request is properly retained, enhancing the stability and reliability of certificate status checking.

In addition to OCSP, we also fully support Certificate Revocation Lists (CRL). However, OCSP is the preferred method for real-time certificate status validation. OCSP provides a more efficient and timely approach to checking certificate revocation status and remains a key feature of our SSL/TLS library.

These updates reflect wolfSSL’s ongoing commitment to providing secure, efficient SSL/TLS solutions with robust certificate validation features. To learn more about wolfSSL’s OCSP support, visit our OCSP page.

What Algorithms Will Your Customers Need by 2035?

As we approach the end of the year, it is a good time to reflect on where you are in your transition to post-quantum cryptography. Have you started? Do you have a plan in place? If so, what does your timeline look like? Most importantly, does it meet the requirements of your customers? If you are not sure what those requirements are, then you will find the following document very enlightening.

NIST (National Institute of Standards and Technology) recently published a document known as IR 8547.

It is titled “Transition to Post-Quantum Cryptography Standards” and gives detailed assessments of the threat from quantum computers including explanations of cryptographic components in software and communications infrastructure and migration to post-quantum cryptography considerations. The document is only 20 pages and the language is very accessible even to the layman; no Ph.D required.

The most notable guidance within this document is section 4 titled “Towards a PQC Standards Transition Timeline”. It begins by referencing National Security Memorandum 10 (NSM-10) which was issued by the Whitehouse. Directly quoting from it:

“Any digital system that uses existing public standards for public?key cryptography, or
that is planning to transition to such cryptography, could be vulnerable to an attack by a
Cryptographically Relevant Quantum Computer (CRQC). To mitigate this risk, the United
States must prioritize the timely and equitable transition of cryptographic systems to
quantum-resistant cryptography, with the goal of mitigating as much of the quantum
risk as is feasible by 2035.”

To summarize the rest of the section, ECDSA, EdDSA, RSA, FFDH, and ECDH are all disallowed for usage by 2035. By then, their post-quantum counterparts – ML-DSA, SLH-DSA, LMS, XMSS, and ML-KEM – should be used in their place. 2035 is only 10 years away. How does that fit in with your product development cycle and cryptographic certification timelines?

Perhaps there will be some exceptions, but likely those will be hard to come by, expensive, and require long processing time as they will be on a case-by-case basis. The better situation to be in is to simply be ready and have completed your migration to post-quantum cryptography.

Want to get started? We at wolfSSL are very proud that we already have post-quantum algorithms implemented and you can try them out in wolfSSL, wolfSSH, wolfMQTT and wolfBoot! Go ahead and get started to better understand how these new algorithms will affect your products and your customer’s user experience!

Post-Quantum KEM TLS 1.3 Security Level Fix

Recently, in our 5.7.4 release we fixed a bug in our TLS 1.3 post-quantum key exchange implementation. The bug was that when users wanted to use post-quantum Kyber (ML-KEM) for key establishment in TLS, the security level the user picked was being ignored by the wolfSSL library.

The fix can be found here.

With this simple fix, you can be assured that you are negotiating post-quantum key establishment at the desired security level. This is true for both Kyber (ML-KEM) on its own as well as hybridized with ECDH.

Users building with –enable-kyber and enabling PQC cipher suites with TLS 1.3 connections are recommended to update the version of wolfSSL used.

Big thanks to Daniel Correa for finding and reporting the bug.
