Email certificates help make email more secure in two ways:

• A digital signature is a mathematical algorithm that helps validate that a message is from the stated sender, and that the content of the message has not changed since it was sent.
• Encryption is a way to send an encoded message that can only be decoded by someone with the proper key.

KU uses InCommon certificates for email signing and encryption, and digital certificates are available to all current KU faculty, staff, and student staff. You can digitally sign email to anyone — on or off campus — with no special setup required by the recipient.
