A custom CloudFormation resource for managing SecureString parameters in AWS SSM. It addresses the limitation in AWS CloudFormation regarding the creation of SecureString parameter types. See AWS Resource SSM Parameter.

• Limited to Node.js version 16, as later versions do not preload the aws-sdk module.
• Fixed delete operation for SSM parameters.
• Appends a random string suffix to parameters.
• Enforce SecureString only parameter types.
• The cfn-response module is preloaded only when using the ZipFile Lambda Code property, restricting the ability to install additional packages; this is the actual restriction blocking further Node.js upgrades.

• infrastructure.yml: Contains the definition of the custom resource.
• example.yml: Showcases the usage of the custom resource.
• Makefile: Contains command to deploy the CloudFormation stack.
