Our shiny new SHA1 encryption has been deprecated already. Google Chrome has recently announced a change that affects our SHA1 encrypted SSL certificate. Users interacting with NukeWorker would see warnings in the Chrome browser which would gradually increase in severity starting in the next few months if the certificate is not reissued using the SHA256 hash algorithm. -- I have started this process. I just wanted to let everyone know in case something wonky happens.
