Python 使用 nacl 生成密钥对

import nacl.signing
import nacl.public

def generate_ed25519_keypair():
    "return (public_key, private_key)"
    signing_key = nacl.signing.SigningKey.generate()
    pk = signing_key.verify_key._key
    sk = signing_key._signing_key
    return (pk, sk)


def generate_curve25519_keypair():
    "return (public_key, private_key)"
    sk = nacl.public.PrivateKey.generate()
    pk = sk.public_key
    return (pk, sk)
