| Hi, I find myself wanting to quickly parse/decode/unescape sensitive data via randomly found sites but cannot. I wonder if there is an existing solution to making sure a random base64 encoder site will not phone home with my data. Specific use cases: - Parse a JWT using jwt.io - Encode/unescape/parse data from a specific format (base64, protobuf, ...) - Hashing a password - Generating Bitcoin wallet using bitaddress.org The solutions I end up doing: - Finding a way to do it offline (in a terminal) or using/writing a script I can safely audit. - Load up a VM, load the site, cut it from network, make use of the site and throw away the VM. I am debating on creating a Browser extension to solve this problem, but wanted to get ideas from you to see if I am missing something that already exists. The extension would have an isolate functionality that would: - Cut off network access for a tab - Cut off access to other tabs (Not sure how to do this, temporary containers in Firefox?) - Listen for tab close event and clear all browser data for that site (cookies, storage, workers, history etc...) What do you think? |
