SNSMessageValidator
✓ from sns_message_validator import SNSMessageValidator
✗ from aws_sns_message_validator import SNSMessageValidator

Validate an AWS SNS message by passing the full JSON message string.

import json from aws_sns_message_validator import SNSMessageValidator validator = SNSMessageValidator() message = { 'Type': 'Notification', 'MessageId': '...', 'TopicArn': '...', 'Subject': '...', 'Message': '...', 'Timestamp': '...', 'SignatureVersion': '1', 'Signature': '...', 'SigningCertURL': '...', 'UnsubscribeURL': '...' } result = validator.validate_message(json.dumps(message)) print(result)
Debug
Known issues
gotchaThe validate_message method expects a JSON string, not a dict. Passing a dict will cause a TypeError.
fix
Always json.dumps() your dict before calling validate_message.
affects: all
gotchaCertificate URL must be HTTPS and point to a valid AWS certificate. The library does not validate the URL beyond downloading it.
fix
Ensure the SigningCertURL is always an AWS https URL (e.g., https://sns.us-east-1.amazonaws.com/...).
affects: all
deprecatedThe library uses md5 which is deprecated; some Python environments may raise warnings.
fix
Ignore warnings or use a different library like 'aws-encryption-sdk' for strict compliance.
affects: 0.0.5
