Presharedkey support about wireguard-rs HOT 8 CLOSED

Hi @teon

Would it be possible to have a link to that roadmap ? I couldn't find it on github. Is it public ?

Best,

Right now we do not support pre-shared key, but we will put this on the roadmap.

from wireguard-rs.

fwiw i'm using this as a workaround at the moment:

let mut file = NamedTempFile::new()?;
writeln!(file, "{}", preshared_key.to_string());
let path = file.into_temp_path();
println!("wrote psk to file {:#?}", path);

let output = std::process::Command::new("wg")
.args(["set", interface_name, "peer", &peer_public_key.to_string(), "preshared-key", path.to_str().unwrap()])
.output()?;

path.close()?;

from wireguard-rs.

Hey @master-hax ,

Thank you for the work around.
Unfortunately I can't write on the disk and I can't process command from the binary due to security reasons, so I guess I'll have to wait for @wojcik91 to implement it.

Best,

Hi @Ange-Cesari & @master-hax!
I did not have time to look into this yet, but from what I know the Peer struct already includes an optional preshared_key field.

Did you try it out?

Yes I've tried it out.

The key passed to the struct is persisted and looks like it gets applied when the interface configuration is read back.

However, if we double-check the peer with wg showwe can see that the preshared key is not set.

Hey, @wojcik91

I tried too,

It seems it's not a structure issue, it's an interface configuration issue and more like how are applied the different fields

Hi.
There was indeed a bug in Linux implementation. Should be resolved now by #21. I'll make a new patch release shortly.
