1. A self signed ML-DSA certificate can be used by NSS server and NSS client can establish a successful connection to it 2. An NSS server can be used with a typical certificate chain (CA, subCA, server cert), and NSS client can establish a successful connection to it. 3. Client certificate based authentication with ML-DSA keys and certificates works 4. Interoperability with OpenSSL (as both server or client) is tested 5. All three key sizes: ML-DSA-44, ML-DSA-65, and ML-DSA-87 are tested. 6. Interoperability of private keys with OpenSSL (through PKCS#12) is verified

.NSS supports ML-DSA keys With this update, the Network Security Services (NSS) database now supports using Module-Lattice-Based Digital Signature Algorithm (ML-DSA) keys. ML-DSA is a new signing algorithm approved by the National Institute of Standards and Technology (NIST) as resistant to attacks from a Cryptographically Relevant Quantum Computer (CRQC).
