Following my conversation with BlackBerry CEO John Chen yesterday, I received a message from a senior product manager at BlackBerry who is responsible for security product management. He thanked me for bringing this to their attention and says they have reached out to Let’s Encrypt to commence execution of their root certificate integration agreement. They are preparing a new build of their BlackBerry 10 software for Q2 release which the root certificates could be added to. They’re also willing to add the required certs to their custom Android build, which runs the BlackBerry Priv phone. Good news all around – I look forward to seeing Let’s Encrypt recognized by BlackBerry.
