Azure SDK for Rust - Azure Identity Crate

Azure Identity crate for the unofficial Microsoft Azure SDK for Rust. This crate is part of a collection of crates: for more information please refer to https://github.com/azure/azure-sdk-for-rust. This crate provides mechanisms for several ways to authenticate against Azure

Several implementations of azure_core::auth::TokenCredential trait are available:

• DefaultAzureCredential
• EnvironmentCredential
• ImdsManagedIdentityCredential
• AzureCliCredential
• AutoRefreshingTokenCredential

There are several examples available. The service examples mostly use AzureCliCredential.

To authenticate using the client credential flow, you can do the following:

```rust use azureidentity::clientcredentials_flow; use oauth2::{ClientId, ClientSecret}; use url::Url;

use std::env; use std::error::Error;

[tokio::main]

async fn main() -> Result<(), Box> { let clientid = ClientId::new(env::var("CLIENTID").expect("Missing CLIENTID environment variable.")); let clientsecret = ClientSecret::new( env::var("CLIENTSECRET").expect("Missing CLIENTSECRET environment variable."), ); let tenantid = env::var("TENANTID").expect("Missing TENANTID environment variable."); let subscriptionid = env::var("SUBSCRIPTIONID").expect("Missing SUBSCRIPTIONID environment variable.");

let client = reqwest::Client::new();
// This will give you the final token to use in authorization.
let token = client_credentials_flow::perform(
    client,
    &client_id,
    &client_secret,
    &["https://management.azure.com/"],
    &tenant_id,
)
.await?;
Ok(())

} ```

The supported authentication flows are: * Authorization code flow. * Client credentials flow. * Device code flow.

This crate also includes utilities for handling refresh tokens and accessing token credentials from many different sources.
