What I would like even more than WG adoption is code point registration in the TLS SignatureScheme registry of ML-DSA and SLH-DSA. OpenSSL 3.5 Long-Term Support (LTS) which shipped a week ago already implement all the algorithms below. What are we waiting for? Thank to the OpenSSL team for acti

I strongly support adoption. OpenSSL 3.5 LTS already support draft-tls-westerbaan-mldsa. TLS is far more than the Web and the WebPKI. And PKI is far more than CABF Baseline Requirements. Critical infrastructure like telecom and national security systems will deploy PQC authentication soon. Chee
