Certificate Expiration Dashboard

A certificate is a digital document that is used to prove the identity of an individual or organization. In the context of computer systems, a certificate is typically used to verify the identity of a website or server, and to ensure that data transmitted between the two is secure.

Certificates are issued by a certification authority (CA), which is a trusted third party that verifies the identity of the individual or organization requesting the certificate. Once issued, the certificate is stored on the website or server, and is used to encrypt data transmitted between the website or server and a user's device. This encryption helps to protect sensitive information, such as passwords and credit card numbers, from being intercepted by malicious actors.

This tool queries publicly-available data from Certificate Transparency Logs (CTL) to show what certificates registered to the tamu.edu domain are about to expire, and what CA they are registered with. You can use this tool to look up certificate expiration dates for subdomains of tamu.edu and subscribe to get email notifications when new certificates enter an expiration range.
