Hot on the heels of our work with dual algorithm certificates in TLS 1.3, it is now time to announce that we are going to be working on chameleon certificates! No, we are not talking about certified colour shifting lizards! Chameleon certificates are specified in the IETF draft. While it might seem like a long […]
Read MoreMore TagIs post-quantum cryptography still on the roadmap?
In case you were wondering, the answer is a resounding YES!! We’ve been hard at work making post-quantum algorithms first class citizens in our products. Have a look at the list of post-quantum related changes made in our latest release of wolfSSL 5.7.4: Replaced the use of pqm4 with wolfCrypt’s implementations of Kyber (ML-KEM) and […]
Read MoreMore TagImproved 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 […]
