| Apr 9, 2024 at 22:55 | comment | added | Myria | Yes, but it would be slower. Ed25519 and Curve25519 are isomorphic (if you handle Curve25519's degenerate points correctly), so you can convert between the two. It gets a bit complicated, but it can be done. However, there's not much reason to do this - just use a Curve25519 implementation. | |
