@thankful-midnight-89472 Hi, not sure what OS your on, but the command

openssl rand -base64 32

creates a randoms string eg: pO9eiL72pV7ezrcE/A2k10dY7l5pCbG9JhAtaCSfZ7Q= just a random secrets, AFAIK it ends in a =

base64 encoding uses '=' as a padding character and you can have one or two of them with an arbitrary base64 encoded string. There's also a "web format" for base64 encoding which leaves off the = since that's irritating in a URL, but it's the same otherwise.
