How can I validate a digital signature?

A digital signature (standard electronic signature) takes the concept of traditional paper-based signing and turns it into an electronic "fingerprint.” This "fingerprint,” or coded message, is unique to both the document and the signer and binds them together. Digital signatures ensure the authenticity of the signer. Any changes made to the document after it has been signed invalidate the signature, thereby protecting against signature forgery and information tampering. As such, digital signatures help organizations sustain signer authenticity, accountability, data integrity and the non-repudiation of signed electronic documents and forms.

Simply right-click on the signature and choose the “Validate” option. Validating the digital signature enables the recipient to authenticate the identity of the signer and view the reason, date and time of the signature. Validation guarantees the signed document was not tampered with and/or modified, ensuring the signer was a valid employee, for example, at the time of signing the document. CoSign allows receiving parties to validate signatures without requiring software installation. In some cases third parties will need to download your certificate from CoSign Nation in order to verify your digital signature. Note: Validating a signature varies slightly according to the application and its version.
