jwt_compact::traits::Algorithm is not implemented for Ed25519

[supchuck]

I am currently receiving the error mentioned above when I try to compile code utilizing a TokenSigner, however did not receive any such error when using a CookieSigner. This only began after recently updating to version 0.3.0. My code is as follows:

let token_signer = TokenSigner::<UserJWT, _>::new()
        .signing_key(key_pair.sk.clone())
        .access_token_name("user_access_token")
        //Token's lifespan is 2 hours, then requires reauthentication
        .refresh_token_lifetime(chrono::Duration::minutes(120))
        .algorithm(Ed25519)
        .build()
        .unwrap();

The full error output is as follows (this output is also produced if I copy and paste the example code on docs.rs for a TokenSigner):

Im gone take a look at it when I get home in about 10 hours.

[michaelvanstraten]

Have you added one of the Features respective to their implementation?

[supchuck]

Using exonum-crypto, I tried:

jwt-compact = {version = "0.7.0", features=["exonum-crypto"]}

as well as the beta version, just to see if there was any difference,

jwt-compact = {version = "0.8.0-beta.1", features=["exonum-crypto"]}

both of which led to the error.

Since, I've switched to ed25519-compact and received the error on 0.8.0-beta.1 of JWT-compact but when I used the current version (0.7.0), I do appear to have any issue.

jwt-compact = {version = "0.7.0", features=["ed25519-compact"]}

I plan to test it further tonight as well but am not able to access my computer at the moment (away from the house).

[michaelvanstraten]

It would be great if you could share a minimal example to reproduce the error.

[supchuck]

Here is the version that works; I commented out the exonum-crypto that always fails so you can uncomment it and switch between the two.. When Cargo.toml (below) is switched to 0.8.0-beta.1 for jwt-compact using ed25519-compact, it will fail. It fails each time when using exonum-crypto for jwt-compact in versions 0.7.0 or 0.8.0-beta.1. I do have a working program using jwt-compact 0.7.0 with ed25519-compact. I also just found out that exonum-crypto is no longer available for linux so I'm not that concerned about continuing its use but thought I would still pass this along.

Sorry Mate, your minimal example compiles on my system just fine.

Here is the head of my os-release (x64):

PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

Could you share some info about your system?

I would also try to delete the cargo build cache:

cargo clean

@supchuck does this issue still a cure?

I've been having this same issue, resolved it by reverting back to jwt_compact to 0.7.0. I've been stuck on this for a few days now and I can't make any sense of what must be going wrong. I can only assume that jwt_compact 0.8 introduced some module layout changes.

[michaelvanstraten]

I will take a look.
