Validating is essential, easy and free!

Do you receive electronically signed documents? Great, but do you know if these documents are indeed digitally signed by the right person? Omitting the verification step exposes you to cast doubt on the identity and the skill set of the signer(s) and ultimately the quality and value of the documents in question.

Questions & Answers

What are the criteria to ensure that a signature is valid?

A signature is recognized as being valid if the certificate associated with the signer is valid (not revoked) at the time of signing and if the certificate was issued by a recognized certificate authority.
A signature is invalid if it does not meet the conditions previously mentioned, if validation proof was not included at the time of signing or if the signer’s certificate has expired.

What is the purpose of signature validation?

The complete validation of the signature is just as important as the act of signing the document. Before publishing, accepting or archiving a document, validating the identity of your documents’ signers and ensuring that they are duly authorized to sign is essential. It is also important to verify if your document will be able to be read for decades to come and if it was altered after it was signed.
