Document Verification

Every document generated by Klervex includes a SHA-256 hash for tamper-proof verification.

How It Works​

  1. When a document is generated, a SHA-256 hash of its content is computed
  2. The hash is stored permanently in the Klervex database
  3. The hash is printed in the document footer
  4. Anyone can verify the document at klervex.com/verify

Verifying a Document​

Via Web Portal​

  1. Go to klervex.com/verify
  2. Enter the document hash (found in the document footer)
  3. The system confirms:
    • Whether the hash exists
    • When the document was generated
    • Document type and basic metadata

Each generated document has a shareable verification link. The recipient clicks the link and sees the verification status directly.

What Verification Proves​

  • The document was generated by Klervex
  • The document has not been modified since generation
  • The timestamp of generation

What Verification Does Not Prove​

  • Accuracy of the data (that's what validation is for)
  • Legal binding status
  • Whether the document was accepted by customs
