public class SecretValue
extends Intrinsic

Work with secret values in the CDK.

Constructs that need secrets will declare parameters of type SecretValue.

The actual values of these secrets should not be committed to your repository, or even end up in the synthesized CloudFormation template. Instead, you should store them in an external system like AWS Secrets Manager or SSM Parameter Store, and you can reference them by calling SecretValue.secretsManager() or SecretValue.ssmSecure().

You can use SecretValue.unsafePlainText() to construct a SecretValue from a literal string, but doing so is highly discouraged.

To make sure secret values don't accidentally end up in readable parts of your infrastructure definition (such as the environment variables of an AWS Lambda Function, where everyone who can read the function definition has access to the secret), using secret values directly is not allowed. You must pass them to constructs that accept SecretValue properties, which are guaranteed to use the value only in CloudFormation properties that are write-only.

If you are sure that what you are doing is safe, you can call secretValue.unsafeUnwrap() to access the protected string of the secret value.

(If you are writing something like an AWS Lambda Function and need to access a secret inside it, make the API call to GetSecretValue directly inside your Lamba's code, instead of using environment variables.)

Example:

 // Read the secret from Secrets Manager
 Pipeline pipeline = new Pipeline(this, "MyPipeline");
 Artifact sourceOutput = new Artifact();
 GitHubSourceAction sourceAction = GitHubSourceAction.Builder.create()
         .actionName("GitHub_Source")
         .owner("awslabs")
         .repo("aws-cdk")
         .oauthToken(SecretValue.secretsManager("my-github-token"))
         .output(sourceOutput)
         .branch("develop")
         .build();
 pipeline.addStage(StageOptions.builder()
         .stageName("Source")
         .actions(List.of(sourceAction))
         .build());

protected SecretValue(software.amazon.jsii.JsiiObject.InitializationMode initializationMode)

SecretValue

public SecretValue(java.lang.Object protectedValue,
                   IntrinsicProps options)

Construct a SecretValue (do not use!).

Do not use the constructor directly: use one of the factory functions on the class instead.

Parameters:

protectedValue - This parameter is required.

options -

Method Detail

cfnDynamicReference

public static SecretValue cfnDynamicReference(CfnDynamicReference ref)

Obtain the secret value through a CloudFormation dynamic reference.

If possible, use SecretValue.ssmSecure or SecretValue.secretsManager directly.

Parameters:

ref - The dynamic reference to use. This parameter is required.

cfnParameter

public static SecretValue cfnParameter(CfnParameter param)

Obtain the secret value through a CloudFormation parameter.

Generally, this is not a recommended approach. AWS Secrets Manager is the recommended way to reference secrets.

Parameters:

param - The CloudFormation parameter to use. This parameter is required.

isSecretValue

public static java.lang.Boolean isSecretValue(java.lang.Object x)

Test whether an object is a SecretValue.

Parameters:

x - This parameter is required.

plainText

@Deprecated
public static SecretValue plainText(java.lang.String secret)

Deprecated. Use `unsafePlainText()` instead.

(deprecated) Construct a literal secret value for use with secret-aware constructs.

Do not use this method for any secrets that you care about! The value will be visible to anyone who has access to the CloudFormation template (via the AWS Console, SDKs, or CLI).

The only reasonable use case for using this method is when you are testing.

Parameters:

secret - This parameter is required.

resourceAttribute

public static SecretValue resourceAttribute(java.lang.String attr)

Use a resource's output as secret value.

Parameters:

attr - This parameter is required.

secretsManager

public static SecretValue secretsManager(java.lang.String secretId,
                                         SecretsManagerSecretOptions options)

Creates a `SecretValue` with a value which is dynamically loaded from AWS Secrets Manager.

Parameters:

secretId - The ID or ARN of the secret. This parameter is required.

options - Options.

secretsManager

public static SecretValue secretsManager(java.lang.String secretId)

Creates a `SecretValue` with a value which is dynamically loaded from AWS Secrets Manager.

Parameters:

secretId - The ID or ARN of the secret. This parameter is required.

ssmSecure

public static SecretValue ssmSecure(java.lang.String parameterName,
                                    java.lang.String version)

Use a secret value stored from a Systems Manager (SSM) parameter.

Parameters:

parameterName - The name of the parameter in the Systems Manager Parameter Store. This parameter is required.

version - An integer that specifies the version of the parameter to use.

ssmSecure

public static SecretValue ssmSecure(java.lang.String parameterName)

Use a secret value stored from a Systems Manager (SSM) parameter.

Parameters:

parameterName - The name of the parameter in the Systems Manager Parameter Store. This parameter is required.

unsafePlainText

public static SecretValue unsafePlainText(java.lang.String secret)

Construct a literal secret value for use with secret-aware constructs.

Do not use this method for any secrets that you care about! The value will be visible to anyone who has access to the CloudFormation template (via the AWS Console, SDKs, or CLI).

The only reasonable use case for using this method is when you are testing.

Parameters:

secret - This parameter is required.

resolve

public java.lang.Object resolve(IResolveContext context)

Resolve the secret.

If the feature flag is not set, resolve as normal. Otherwise, throw a descriptive error that the usage guard is missing.

Specified by:

resolve in interface IResolvable

Overrides:

resolve in class Intrinsic

Parameters:

context - This parameter is required.

unsafeUnwrap

public java.lang.String unsafeUnwrap()

Disable usage protection on this secret.

Call this to indicate that you want to use the secret value held by this object in an unchecked way. If you don't call this method, using the secret value directly in a string context or as a property value somewhere will produce an error.

This method has 'unsafe' in the name on purpose! Make sure that the construct property you are using the returned value in is does not end up in a place in your AWS infrastructure where it could be read by anyone unexpected.

When in doubt, don't call this method and only pass the object to constructs that accept SecretValue parameters.
