Depends on what you call 'crypto libraries', but: LibSodium (C, so can have
bindings in any language), ed2curve-js (JavaScript), agl/ed25519 (Go),
Chaos.NaCL (C#), orlp/ed25519 (C), ... OpenSSL has only recently gotten
Ed25519 support, so they might get a similar conversion function eventually
(given it's in libsodium). If you follow the "XEdDSA is simple to
implement" school, then this conversion is even simpler to implement in the
library of your choice.
