Best library to generate Ed25519 signatures?

andreamancuso · May 26, 2025, 9:01pm

Hello,
I need to generate Ed25519 signatures and came across GitHub - ahrefs/ocaml-sodium: Binding to libsodium 1.0.9+, a shared library wrapper for djb's NaCl
Should I use that or hacl-star? Or even mirage-crypto-ec?

Thanks!

For now I am going to try out ahrefs’ fork of sodium.
