Why Digitally Sign?

Placing a digital signature on a document proves the information originated with the signer and that the document has not been altered, allowing secure electronic document workflows to replace tedious, paper-based processes.

Authenticity -the digital signature helps to verify and assure that the signer (such as the document author or the email sender) is who he or she claims to be
Integrity - the digital signature helps to assure that the content of the document or email has not been changed or tampered with since it was digitally signed
Non-repudiation - the digital signature helps to prove to all parties the origin of the signed content. On the contrary, "Repudiation" refers to the act of a signer's denying any association with the signed content.
