Cryptographically Secure Webhook Verification System

security webhooks cryptography authentication
Prompt
Develop a robust webhook verification system that uses multi-factor authentication tokens, implements sliding window replay attack prevention, and supports dynamic key rotation. Create a solution that generates ephemeral HMAC-SHA256 signatures with embedded timestamp and request-specific nonce, includes automatic key expiration, and provides granular permission scopes for different webhook endpoints.
