ML-DSA is a post-quantum signature scheme that was recently standardized by NIST. Keys and signatures are pretty large, not making it a drop-in replacement for classical signature schemes. But if you are shipping keys that may still be used in 10 years or whenever large quantum computers able to break ECC arrive, it that ever happens, and you don't have the ability to replace these keys, ML-DSA is for you. Performance is great, verification is faster than Ed25519 / ECDSA. I tried manual vectorization, but it wasn't worth it, the compiler does at good job at auto-vectorization already.
