This Python script updates an SSL certificate on a Synology DiskStation

Assumptions

This script assumes that you have already imported the certificate into Synology once. This script looks for a certificate with the same common name as the certificate that was issued. For example, if your certificate is for www.example.com, the script will attempt to update the equivalent Synology certificate with the common name www.example.com
