Hi @ultrainstintgoku, thanks for reaching out. You may want to create your own x25519 key pair so you can run the server. And you need your own apple push service certificate to make the server work. :)

Hello @RyanRory . Thanks for the update . I have Created the x25519 key pair using the following command openssl genpkey -algorithm x25519 -out x25519_private_key.pem . After running the server i am getting a error as

shared_secret = _curve25519.make_shared(server_privkey_bytes, client_pubkey_bytes) ValueError: input must be 32-byte string 500 error . is there any specific method to used to create a keys . and also need some explanation about how to create public key (hex) which is used inside the session to connect with the server

You can use a python script to generate the key pair, here is an example:

    random = get_random_bytes(32)                      # The private key 32 bytes
    priv = _curve25519.make_private(random)
    print(priv.hex())
    pub = _curve25519.make_public(priv)
    print(pub.hex())

I'll update the README to include this info.

@RyanRory Why does oxend not create a public key called key_ed25519.pub and key_X25519.pub on launch instead? The step could be unnecessary, actually.

For anybody else finding this: oxend-sn-keys generate FILENAME generates a new private key while printing the public key.
