How Signature Verification Works
Encrypted Hash and Timestamp

A unique encrypted hash is generated.
The exact signing time is recorded.
This data ensures the signature cannot be altered or reused.
Signature in PDF Exports
When exporting a submission as a PDF:
The drawn signature is displayed.
The timestamp and encrypted hash are included for verification.
Where Signatures Are Stored
Signatures are saved on the contact record.
They appear under the custom field group assigned during setup.
Submission records also display the signature, timestamp, and hash.
Common Issues and Fixes
Signature Field Not Appearing
Confirm the field is added via Add Object Fields, not Quick Add.
Ensure the field object matches the form object.
Signature Not Saving
