aws-sns-message-validator
Validator for AWS SNS messages.
Decision gist · record as of 2026-08-14
Yes, if you need SNS message validation and can accept dormant maintenance. The package solves a real gap in the AWS SDK and has no known vulnerabilities. However, verify the license terms first, and be aware that the last release was in February 2022 and the repository has not been updated since October 2023—you will not receive security patches or compatibility updates if AWS SNS specifications change.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python >= 3.6; the package is dormant and may not be tested against modern Python versions.
- Low install friction with three common runtime dependencies.
- Maintenance is dormant—last release was in February 2022 and the repository has not received commits since October 2023, so security patches or compatibility updates are unlikely.

What it is and what it does
This package solves a specific gap in the AWS SDK for Python: validating and verifying the authenticity of messages received at an HTTP endpoint subscribed to an SNS topic. AWS SNS sends HTTP POST requests to subscriber endpoints, and each message includes a cryptographic signature that must be verified before processing. The package implements this verification logic according to the official AWS documentation, which AWS itself does not provide in the Python SDK (though example code exists for Java).
The package depends on requests, requests-cache, and cryptography to handle HTTP operations and signature verification. It is designed to be integrated into a web framework like Flask to validate incoming SNS notifications before your application processes them. The repository includes a Flask example showing typical usage patterns.
Use it for
- Validate SNS messages at an HTTP endpoint before processing them in a web application.
- Verify the authenticity of SNS notifications to prevent processing forged or tampered messages.
- Implement a secure SNS HTTP subscriber without duplicating signature verification logic.
