Sceau Laravel Package

Sceau (French for "seal") brings tamper-evident sealing to Laravel applications. It stamps Eloquent models — or arbitrary payloads — with a deterministic cryptographic signature, so any later modification, accidental or malicious, is immediately detectable. Instead of hand-rolling hashing logic in every project, you attach a seal via a simple trait or helper and verify it with a single call, keeping integrity checks consistent across your codebase.

• One-line trait/helper to seal models and payloads
• Deterministic signatures for repeatable verification
• Configurable hashing driver and secret via Laravel config
• Detect and reject tampered records before persisting
• Artisan command to (re)seal existing data in bulk
