Good morning,
I am currently extending uncloud [0] to support wireguard tunnels and keys. At the moment it is not entirely clear how to verify that a certain string is a valid wireguard key. I first tried checking that it is valid base64, but not all base64 strings are valid wireguard keys. Then I tried using `echo $key | wg pubkey && echo ok` - which seems to check the key format, however the intended behaviour here is misused. Does anyone have a pointer on how to reliably identify wireguard public keys? Is the wireguard key always 32 bytes when decoded from base64? Tests with a number of public keys seems to indicate that.
