Crazy idea: would it be possible to encrypt notes (from the browser) and upload it to your server?
Doable, I just need to find a way to encrypt them without the need to import an entire lib for that (i.e crypto-js). I want to keep the script as simple and clean as possible (no jquery, etc...). I'll probably add a local import/export as json soon.
Then please answer my question, Is it safe to use?
People seem inclined to like things from open source, but since Tampermonkey is from closed sources then security questions regarding privacy or such seem worth asking. Instead of blabbering, I'm just telling you I haven't tried it.
I have been using Tampermonkey for years. AFAIK, it is safe as long as you know which scripts you're importing. It's just easier than creating an extension for every script I use (I currently have 3 for the forum - enhanced merits, this one, and to quote posts on locked threads).
