About EVE Seal

The EVE Sealis a cryptographic integrity layer built into every document issued by the EVE system (Evidence & Verification Engine). It guarantees that the document has not been altered since it was generated.

When a document is created, a SHA-256 hash is computed over the entire PDF content and appended as a tamper-evident trailer. Any change to the document — even a single character — produces a completely different hash, making tampering immediately detectable.
