​
Configure Access Keys

The SDK needs to be configured with your access key id and your secret access key, which is available in your Locker Secrets Dashboard. These keys must not be disclosed. If you reveal these keys, you need to revoke them immediately. Environment variables are a good solution and they are easy to consume in most programming languages.

​
Set up credentials on Linux/MacOS

export ACCESS_KEY_ID=<YOUR_ACCESS_KEY_ID>
export SECRET_ACCESS_KEY=<YOUR_SECRET_ACCESS_KEY>

​
Set up credentials on Windows

PowerShell 
$Env:ACCESS_KEY_ID = '<YOUR_ACCESS_KEY_ID>'
$Env:SECRET_ACCESS_KEY = '<SECRET_ACCESS_KEY>'
Command Prompt 
set ACCESS_KEY_ID=<YOUR_ACCESS_KEY_ID>
set SECRET_ACCESS_KEY=<YOUR_SECRET_ACCESS_KEY>
You also need to set api_base value (default is https://api.locker.io/locker_secrets). If you need to set your custom headers, you also need to set headers value in the options param: Now, you can use SDK to get or set values: 
Map<String, String> headers = new HashMap<String, String>() {
    {
        put("CF-Access-Client-Id", "YOUR_CF_ACCESS_CLIENT_ID");
        put("CF-Access-Client-Secret", "YOUR_CF_ACCESS_CLIENT_SECRET");
    }
};
LockerResponseGetterOptions responseGetter = new LockerClient.LockerClientBuilder()
        .setApiBase("YOUR_API_BASE")
        .setHeaders(headers)
        .buildOptions();
LockerClient client = new LockerClient(new LiveLockerResponseGetter(responseGetter));
You can also pass parameters or use the shared credential file ( ~/.locker/credentials ), but we do not recommend these ways. 
import locker.LockerClient;
import locker.exception.LockerError;
import locker.model.Secret;
import locker.param.secret.SecretRetrieveParams;

public class LockerExample {
    public static void main(String[] args) {
        LockerClient client = new LockerClient("YOUR_ACCESS_KEY_ID", "YOUR_ACCESS_KEY_SECRET");
        try {
            Secret secret = client.secrets().retrieve("YOUR_SECRET_KEY", Secret.class);
            System.out.println(secret);
        } catch (LockerError e) {
            e.printStackTrace();
        }
    }
}

​
List Secrets

Use .list() method to list all secrets in project 
String secrets = client.secrets().list(String.class);

/**
 *  return a list of secrets
 * */

Class<? super LockerCollection<Secret>> type = new TypeToken<LockerCollection<Secret>>() {
}.getRawType();
LockerCollection<Secret> secretList = (LockerCollection<Secret>) client.secrets().list(type);

​
Get Secret Values

​
Get a secret by key

This function will get the secret value by a key. 
// Get a secret by secret key
Secret secret = client.secrets().retrieve("java_key_1", Secret.class);
String secretValue = client.secrets().retrieve("java_key_1", String.class);

​
Get a secret by key and environment name

You could get a secret value by a secret key and specific environment name 
// Get a secret by secret key and specific environment name
Secret secret = client.secrets().retrieve("java_key_1", Secret.class, "env_name");
String secretValue = client.secrets().retrieve("java_key_1", String.class, "env_name");

​
Create Secrets

Use the .create() function to create a new secret: 
SecretCreateParams createParams = new SecretCreateParams.Builder()
        .setKey("key")
        .setValue("value")
        .setDescription("description")
        .build();
Secret newSecret = client.secrets().create(createParams, Secret.class);
Create a new secret with a specific environment: 
SecretCreateParams createParams = new SecretCreateParams.Builder()
        .setKey("key")
        .setValue("value")
        .setDescription("description")
        .setEnvironment("environment")
        .build();
Secret newSecret = client.secrets().create(createParams, Secret.class);

​
Update Secrets

SecretUpdateParams updateParams = new SecretUpdateParams.Builder()
        .setKey("your_update_secret_key")
        .setValue("your_update_secret_value")
        .setDescription("your_update_secret_description")
        .build();

// Update a secret by secret key
Secret updatedSecret = client.secrets().modify("your_secret_key", updateParams, Secret.class);

// Update a secret by secret key and specific environment name
Secret updatedSecret = client.secrets().modify("your_secret_key", updateParams, Secret.class, "your_secret_env_name");

​
List Environments

Use the .list() function to retrieve all environments in your project: 
Class<? super LockerCollection<Environment>> type = new TypeToken<LockerCollection<Environment>>() {
}.getRawType();
LockerCollection<Environment> listEnvs = (LockerCollection<Environment>) client.environments().list(type);

// Or retrieve as a JSON string
String envs = client.environments().list(String.class);

​
Retrieve an Environment

To retrieve an environment by name, use .retrieve(): 
Environment environment = client.environments().retrieve("your_env_name", Environment.class);

​
Create an Environment

To create a new environment, use .create(): 
EnvironmentCreateParams createEnvParams = EnvironmentCreateParams.builder()
        .setName("your_env_name")
        .setExternalUrl("your_env_external_url")
        .setDescription("your_env_description")
        .build();
Environment newEnv = client.environments().create(createEnvParams, Environment.class);

​
Update an Environment

EnvironmentUpdateParams params = EnvironmentUpdateParams.builder()
        .setName("your_update_env_name")
        .setExternalUrl("your_update_env_external_url")
        .setDescription("your_update_env_description")
        .build();
Environment updatedEnv = client.environments().modify("your_env_name", params, Environment.class);

​
Error Handling

Locker Secret SDK offers some kinds of errors. They can reflect external events, like invalid credentials, network interruptions, or code problems, like invalid API calls. If an immediate problem prevents a function from continuing, the SDK raises an exception. It’s a best practice to catch and handle exceptions. To catch an exception, use Java’s try/catch syntax. Catch LockerError or its subclasses to handle Locker-specific exceptions only. Each subclass represents a different kind of exception. When you catch an exception, you can use its class to choose a response. Example: 
LockerClient client = new LockerClient(
    "95443edf-eb33-4fae-a66d-c264d14e7217",
    "C+NCA5fwzJeCh3R4O3Dw4YLAbJrrvgJt1bJSe1BEhrY="
);
SecretCreateParams params = SecretCreateParams.builder()
    .setValue("your_secret_value")
    .setKey("your_secret_key")
    .setDescription("your_secret_description")
    .build();
try {
    Secret newSecret = client.secrets().create(params, Secret.class);
} catch (LockerError e) {
    e.printStackTrace();
}
In the SDK, error objects belong to LockerError and its subclasses. Use the documentation for each class for advice about how to respond.
NameClassDescription
Authentication Errorlocker.error.AuthenticationErrorInvalid access_client_id or invalid secret_access_key
Permission Denied Errorlocker.error.PermissionDeniedErrorYour credential does not have enough permission to execute this operation
RateLimit Errorlocker.error.RateLimitErrorToo many requests
API Errorlocker.error.APIErrorYou made an API call with the wrong parameters, in the wrong state, or in an invalid way, or something went wrong on Locker’s end
CLI Run Errorlocker.error.CliRunErrorThe encryption/decryption binary runs errors by invalid local data, process interruptions, or invalid secret_access_key

​
Logging

The library can be configured to emit logging that will give you better insight into what it’s doing. There are some levels: debug, info, warning, error. The info logging level is usually most appropriate for production use, but debug is also available for more verbosity. There are a few options for enabling it:
  1. Set the environment variable LOCKER_LOG to the value debug, info, warning or error
$ export LOCKER_LOG=debug
  1. Set log when initializing the Locker object
from locker import Locker

locker = Locker(log="debug")
  1. Enable it through Python’s logging module:
import logging
logging.basicConfig()
logging.getLogger('locker').setLevel(logging.DEBUG)
