It’s the first idea I had when it came to making sure login on my server is secure. Instead of having a small password that relies on my fallinble memory and may be also guessed in a not-completely-rodiculous amount of time.
Meanwhile a fairly small file, something like a 512 byte “user.key”, to be uploaded along with your username, or even just having your username built-in, seems much safer.
I wanted to do some math but I could only find limited calculators for doing calculations with such big numbers so have the amount of possible combinations the file may have:
256^512

What am I missing? I assume I’m missing something, because the idea of something like this going over a lot of smart programmers and developers’ heads does not sound right
I’ll be honest, despite already having a reverse proxy on my home setup I did not think of doing something like that. That sounds like a great idea
