The CDK Construct Library for AWS::Signer
Decision gist · record as of 2026-08-14
No—not for new projects. This is AWS CDK v1, which reached end-of-support on 2023-06-01 and is no longer updated. AWS explicitly recommends migrating to AWS CDK v2. If you are already on CDK v1 and need signing constructs, this package is stable and has no known vulnerabilities, but you should plan a migration. For new work, use the v2 equivalent instead.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- AWS CDK v1 reached end-of-support on 2023-06-01 and is no longer updated; new projects should use AWS CDK v2.
- Low install friction with a stable dependency tree.
- However, this is an AWS CDK v1 package that reached end-of-support on 2023-06-01 and is no longer being updated; AWS recommends migrating to AWS CDK v2 for ongoing support.

What it is and what it does
This package is an AWS CDK Construct Library module that wraps AWS Signer, a managed code-signing service. It lets you define signing profiles and platforms as infrastructure-as-code constructs, specifying signature formats, algorithms, and validity periods for code bundles. The library provides pre-defined signing platforms (AWS_LAMBDA_SHA384_ECDSA, AWS_IOT_DEVICE_MANAGEMENT_SHA256_ECDSA, AMAZON_FREE_RTOS_TI_CC3220SF, AMAZON_FREE_RTOS_DEFAULT) that you can instantiate and configure declaratively.
The package depends on aws-cdk.core, constructs, jsii, publication, and typeguard. It is part of AWS CDK v1, which has been end-of-support since 2023-06-01 and is no longer receiving updates. New projects should use AWS CDK v2 instead; existing v1 users can continue to use this package but will not receive bug fixes or new features.
Use it for
- Define a signing profile for Lambda function code bundles with a specific signature algorithm and validity period.
- Set up code-signing infrastructure for IoT device management using predefined AWS Signer platforms.
- Declare signing templates as part of a larger CDK application to enforce code integrity across deployments.
- Configure FreeRTOS code-signing profiles for embedded systems using AWS Signer platforms.
