This is a sample project demonstrating the use of Spring Shell commands to read secure input from the user, such as passwords.

To build the project, navigate to the project's root directory and run the following command:

./mvnw clean install

To run the application, use the following command:

java -jar spring-shell-samples/spring-shell-sample-secure-input/target/secure-input.jar

You should see a prompt where you can login with auth login. This command will ask you to enter a username and password securely.

The sample application uses an in-memory user store with a single user foo with the password bar. You can use these credentials to log in.

After logging in, you can use the auth change-password command to securely change the password.

This sample also shows how to use the AvailabilityProvider API to restrict access to certain commands based on the user's authentication status. For example, the auth change-password command is only available when the user is authenticated.
