Post-Quantum Algorithms in OpenSSL

Matt Caswell

Recently NIST published a number of post-quantum algorithm standards (ML-KEM, ML-DSA, and SLH-DSA). With these new NIST publications, OpenSSL is now prepared for implementation.

We’ve recently been receiving a lot of questions about these new standards so we wanted to make our position clear:

OpenSSL considering TLS 1.0/1.1 deprecation

Neil Horman

Recently, OpenSSL proposed the deprecation of TLS 1.0/1.1 and solicited community feedback on the idea.

Feedback on the proposal was generally split down the middle, with half of the respondents indicating immediate depreciation with near-term removal was acceptable, while the remainder of the respondents with affirmative opinions noted that they represent, or know of products whose environment disallowed updating to TLS1.2 or later, and would need to re-enable the deprecated features for the foreseeable future.
