Overview
This document explains how to apply for a digital certificate through the University’s Accounts Self-Service website and how to use that digital certificate to sign and encrypt email messages. A digital certificate is a security tool that can be attached to an email message to verify that the sender of the message is who he or she claims to be and that the message has not been altered since it was sent. It can also be used to encrypt email messages.
Detail
Step 1 - Apply
Apply for your digital certificate via the Accounts Self-Service page. You will need a University Computing Account username and password. You must also have secure access to a personal computer to ensure the security and integrity of your digital certificate. After your application has been approved, you will receive an email with a Personal Identification Number (PIN) for retrieving your digital certificate.
Important: You must use the same computer and web browser to retrieve your digital certificate as you did to apply for your certificate. You also cannot apply for a digital certificate from the Student Computing Labs.
Note: If your advertised email address has a prefix between "@" and “.pitt.edu” (for example, dept.pitt.edu), then that will be the address used for your digital certificate. If your advertised email address is blank, then your username@pitt.edu email address will be used for your digital certificate.
