any good resources on how to use std.crypto, i mainly want to generate a pair of private/public keys (if thats even possible with zigs crypto) and then sign a byte array and verify. Thanks.

using ecdsa: https://github.com/ziglang/zig/blob/9f84f7f921d8a74926bb2f0ca1969b7b00f08172/lib/std/crypto/ecdsa.zig#L379-L393
using ed25519: https://github.com/ziglang/zig/blob/9f84f7f921d8a74926bb2f0ca1969b7b00f08172/lib/std/crypto/25519/ed25519.zig#L494-L504 (but use KeyPair.create(null) to generate a random key pair)

is i use ed25519 is it safe to sign more than one message with a key pari or should i regenerate the key pair?

https://security.stackexchange.com/questions/191718/sign-a-lot-of-messages-with-same-private-key seems safe
