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 â even a single character â produces a completely different hash, making tampering immediately detectable.
