aws4

The aws4 package is a lightweight utility that signs requests using AWS Signature Version 4. It can be used independently of the AWS SDK. Unlike @aws-sdk/middleware-signing, which is integrated within the AWS SDK v3, aws4 can be used with any HTTP request tool, providing more flexibility but requiring manual integration.

amazon-cognito-identity-js

This package includes functionality for signing in users and handling tokens with Amazon Cognito. While it is focused on authentication like @aws-sdk/middleware-signing, its scope is specifically tied to Amazon Cognito and does not provide general request signing capabilities for other AWS services.
