| Abstract: | TLS certificates are what is keeping the secure web running, they are the cornerstone of secure HTTPS connections. In this paper we will dive into one of the suppliers of TLS certificates, Let’s Encrypt. They supply their certificates for free and do this at a 90 day validity period after which users need to renew their certificate(s). However, how often do users renew their certificates and are they renewing them for extended periods? Not much is known about this as of yet and this research will answer these questions. Using Certificate Transparency (CT) logs, massive collections of all certificates handed out by a certificate authority, we will try to analyze the user behaviour to find this out. In this research, we find that users generally do this (shortly) after a 60 interval, as recommended by Let’s Encrypt. |
