I want to validate one or more CertifiO digital signatures.

Validating digital signatures is easy and free! Above all, it’s the only way to ensure that digitally signed documents have been authenticated by the right person with the required credentials at the time they affixed their signature or seal.

Note that only our free ConsignO Desktop software can be used to batch validate digitally signed documents, directly from your file explorer.
