Azure Core Authentication client library for JavaScript

The @azure/core-auth package provides core interfaces and helper methods for authenticating with Azure services using Azure Active Directory and other authentication schemes common across the Azure SDK. As a "core" library, it shouldn't need to be added as a dependency to any user code, only other Azure SDK libraries.

Getting started

Installation

Install this library using npm as follows

npm install @azure/core-auth

Key Concepts

The TokenCredential interface represents a credential capable of providing an authentication token. The @azure/identity package contains various credentials that implement the TokenCredential interface.

The AzureKeyCredential is a static key-based credential that supports key rotation via the update method. Use this when a single secret value is needed for authentication, e.g. when using a shared access key.

The AzureNamedKeyCredential is a static name/key-based credential that supports name and key rotation via the update method. Use this when both a secret value and a label are needed, e.g. when using a shared access key and shared access key name.

The AzureSASCredential is a static signature-based credential that supports updating the signature value via the update method. Use this when using a shared access signature.

Examples

AzureKeyCredential

const { AzureKeyCredential } = require("@azure/core-auth");

const credential = new AzureKeyCredential("secret value");
// prints: "secret value"
console.log(credential.key);
credential.update("other secret value");
// prints: "other secret value"
console.log(credential.key);

AzureNamedKeyCredential

const { AzureNamedKeyCredential } = require("@azure/core-auth");

const credential = new AzureNamedKeyCredential("ManagedPolicy", "secret value");
// prints: "ManagedPolicy, secret value"
console.log(`${credential.name}, ${credential.key}`);
credential.update("OtherManagedPolicy", "other secret value");
// prints: "OtherManagedPolicy, other secret value"
console.log(`${credential.name}, ${credential.key}`);

AzureSASCredential

const { AzureSASCredential } = require("@azure/core-auth");

const credential = new AzureSASCredential("signature1");
// prints: "signature1"
console.log(credential.signature);
credential.update("signature2");
// prints: "signature2"
console.log(credential.signature);
