huskarl 0.5.1

Huskarl provides tools for implementing secure OAuth2 clients in rust.

This library provides a number of grant implementations, each of which is configured with a set of parameters that define how the grant/workflow should progress.

The library also provides a caching layer for token responses; and a HTTP authorizer that can be used to make authenticated requests to resource servers.

Examples

Client Credentials Grant

let metadata = AuthorizationServerMetadata::builder()
    .http_client(&http_client)
    .issuer(issuer)
    .build()
    .await
    .unwrap();

let grant = ClientCredentialsGrant::builder_from_metadata(&metadata)
    .client_id(client_id)
    .client_auth(ClientSecret::new(client_secret))
    .dpop(NoDPoP)
    .build();

let token_response = grant
    .exchange(
        &http_client,
        ClientCredentialsGrantParameters::builder()
            .scopes(vec!["test"])
            .build(),
    )
    .await
    .unwrap();

println!(
    "Access token: {}",
    token_response.access_token().token().expose_secret()
);
