@aescling How old? I had the impression that at least in SSH the change from SHA1 and RSA to the elliptic curve stuff was quite recent...

@vaporeon_ Curve25519 was created in 2006; Ed25519 is based on that and seems to have been introduced in 2012? idk maybe that‘s not exactly “old” at this point but it feels weird to me to call Ed25519-based crypto “modern” when it’s more like “finally starting to actually get implemented in mainstream software”

@aescling Surely it hasn't been invented yet for 23,493 years. (It is not *new*, but it is *modern*. Unless you're in the group saying ML-KEM is the only modern cryptosystem worth anything, I guess.)
