How to use CREDA-Stamp

Verify a document in seconds.

CREDA-Stamp allows you to prove whether a document has changed by creating and later verifying a deterministic integrity record.

Create a record

Select the finalized document (for example, a signed or executed file)
Click Generate Record
Download and save the record with the document

The generated record represents the exact contents of the file at that moment.

Verify a document later

Select the document you want to verify
Paste the saved CREDA-Stamp record
Click Verify File

CREDA-Stamp will confirm whether the file matches the original recorded version.

Understanding results

Match verified — The file is identical to the recorded version
No match — The file differs from the recorded version

Best practices

Generate a record immediately after a document is finalized
Store the record with the document (same folder, case file, or archive)
Use verification when document integrity is in question

Important note

CREDA-Stamp verifies whether a file has changed. It does not certify authorship, authenticity, or legal validity of the document.
