Most Common Methods
Verification with a signature validator
There are online services that automatically verify the validity of the signature and certificate.
Verification in PDF reader software
Many electronically signed documents are in PDF format and can be verified directly in applications like Adobe Reader.
The application verifies:
- The signatory's certificate
- Document integrity
- The certification chain
What the System Actually Checks
When you verify an electronic signature, the system confirms:
The signatory's certificate is valid
The certificate was issued by an authorised provider
The document has not been modified since signing
⚠️ If the document is modified after signing, the signature becomes invalid.
