+# auth.provider
+
+AuthProvider package enables you to generate the required access token like Project Scoped Token to authenticate and access Affinidi Trust Network services.
+
+For more information, please visit [https://github.com/affinidi/affinidi-tdk](https://github.com/affinidi/affinidi-tdk)
+
+## Requirements
+
+Building the package requires:
+
+1. Java 1.8+
+2. Maven (3.8.3+)
+
+## Installation
+
+To install the API client library to your local Maven repository, simply execute:
+
+```shell
+mvn clean install
+```
+
+To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:
+
+```shell
+mvn clean deploy
+```
+
+### Maven users
+
+Add this dependency to your project's POM:
+
+```xml
+<dependency>
+  <groupId>com.affinidi.tdk</groupId>
+  <artifactId>auth.provider</artifactId>
+  <version>1.0.0</version>
+</dependency>
+```
+
+### Others
+
+At first generate the JAR by executing:
+
+```shell
+mvn clean package
+```
+
+## Usage
+
+Sample usage to generate Project Scoped Token to call Affinidi TDK clients.
+
+> You can store the required parameters like the Token details into an environment file.
+
+```java
+
+// Import classes:
+import com.affinidi.tdk.authProvider.helper.JwtUtil;
+import com.affinidi.tdk.authProvider.helper.AuthProvider;
+
+public class AuthProviderConsumer {
+  public static void main(String arg[]) {
+        try{
+            // Create an authprovider from the values configured in the environment file
+            AuthProvider authProviderFromEnvFile = new AuthProvider.Configurations().buildWithEnv();
+            String projectToken = authProviderFromEnvFile.fetchProjectScopedToken();
+            System.out.println(projectToken);
+
+            boolean isExistingProjectScopeTokenValid = JwtUtil.validProjectTokenPresent(projectToken, authProviderFromEnvFile.apiGatewayUrl);
+            System.out.println(isExistingProjectScopeTokenValid);
+
+
+            // Alternatively you can create an auth provider by explicitly passing the configurations 
+            AuthProvider authProviderWithPassedValues = new AuthProvider.Configurations()
+                .keyId("")
+                .projectId("")
+                .passphrase("")
+                .projectId("")
+                .tokenId("")
+                .build();
+            String projectToken = authProvider.fetchProjectScopedToken();
+            System.out.println(projectToken);
+
+
+        }catch(Exception e){
+            e.printStackTrace();
+        }
+    }
+}
