Thank, You're the best, now it works fine. That message from the ChatGPT was the key.
Best Regards Petr Documentation: Wireguard API "wireguard_interface_create" message with private/public key must be sent in right decoded values. Keys (string) generated from "wg keygen" command cannot be directly converted to []byte, must be decoded. For Go is the key function - the result is []byte[32]. > sEnc, err := > base64.StdEncoding.DecodeString(cfgWireguardInterface.Cfg.PrivateKey) > > čt 8. 12. 2022 v 11:26 odesílatel Pim van Pelt via lists.fd.io <pim= ipng...@lists.fd.io> napsal: > Hoi Petr, > > I think that the keys in the wireguard plugin are represented > as bytestream, and your 44 character string probably refers to its base64 > representation.
