Introduction
When you receive signed documents through Ledgy, you may want to independently verify the authenticity of the signatures. This article explains how to use Adobe Acrobat Reader to verify different types of electronic signatures and understand their validity status.
Verifying signatures with Adobe Reader
If you want to check the validity of the signatures independent of Ledgy, you can do so with Adobe Acrobat Reader.
You can verify signatures in Adobe Reader using two methods:
Method 1: Right-click on the signature
Open your signed PDF document in Adobe Reader
Locate any signature field in the document
Right-click directly on the signature
Select "Show Signature Properties" from the menu
A dialog box will open showing the signature's validity status and details
Method 2: Using the Signatures Panel
Open the document in Adobe Reader
Click on View > Show/Hide > Navigation Panes > Signatures, or click the Signature Panel button in the document message bar
Note: You can right-click a signature field in the Signatures panel to do most signature-related tasks, including adding, clearing, and validating signatures. In some cases, however, the signature field becomes locked after you sign it.
When digital signatures are validated, an icon appears in the document message bar to indicate the signature status. You can inspect additional status details in the Signatures panel and in the signature properties dialog box.
Signatures panel for digital signatures
The Signatures panel displays information about each digital signature in the current document and the change history of the document since the first digital signature. Each digital signature has an icon identifying its verification status. Verification details are listed beneath each signature and can be viewed by expanding the signature. The Signatures panel also provides information about the time the document was signed, and trust and signer details.
