Answer 1

Before getting secrets from the Azure Key Vault make sure you have access to the key vault. Make sure to login or provide correct Azure credential. you can refer this link for getting secret

Or you execute this powershell command Get-AzureKeyVaultSecret -VaultName 'VaultName' -Name 'sceretName'

Answer 2

It seems that you want to access the azure key vault with application.

1. Register a web app in Azure AD

2. You can get the client id (application id) at the overview

3. Add a secret

4. Assign access policy in key vault

5. Save the policy, so that it will take effect.

6. Code sample

public class KeyVaultTest {

    private static AuthenticationResult getAccessToken(String authorization, String resource) throws InterruptedException, ExecutionException, MalformedURLException {

        String clientId = "dc17****-****-****-****-ea03****a5e7"; // Client ID
        String clientKey = "1YWt******k21";  //Client Secret

        AuthenticationResult result = null;

        //Starts a service to fetch access token.
        ExecutorService service = null;
        try {
            service = Executors.newFixedThreadPool(1);
            AuthenticationContext context = new AuthenticationContext(authorization, false, service);

            Future<AuthenticationResult> future = null;

            //Acquires token based on client ID and client secret.
            if (clientKey != null && clientKey != null) {
                ClientCredential credentials = new ClientCredential(clientId, clientKey);
                future = context.acquireToken(resource, credentials, null);
            }

            result = future.get();
        } finally {
            service.shutdown();
        }

        if (result == null) {
            throw new RuntimeException("Authentication results were null.");
        }
        return result;
    }

    public static void main(String[] args) {
        String vaultBase = "https://jackkv.vault.azure.net/";

        KeyVaultClient keyVaultClient = new KeyVaultClient(new KeyVaultCredentials(){
            @Override
            public String doAuthenticate(String authorization, String resource, String scope) {
                String token = null;
                try {
                    AuthenticationResult authResult = getAccessToken(authorization, resource);
                    token = authResult.getAccessToken();
                } catch (Exception e) {
                    e.printStackTrace();
                }
                return token;
            }
        });

        SecretBundle test = keyVaultClient.getSecret(vaultBase, "test");
        System.out.println(test.value());
    }
}

Update:

If you face connection issues, please check if you have set the firewall for your key vault.

If you set the firewall, please add your IP to the allowed list:
