While we’re talking about asymmetric encryption, can someone explain to me why you can’t decrypt information with the same public key that encrypted it? I understand the analogies (locks on a briefcase, unmixing paint, etc), but I can’t “un-analogize” them to understand what’s actually going on. Encryption keys aren’t physical locks or paint. They’re numbers(?). So why can I encrypt something by multiplying by a known public encryption key, but I can’t decrypt it by dividing by that same known public key?
Discord file url parameters are to prevent using discord as a free cdn. I believe discord plans on actually enforcing expiration later this year or early next year, at which point those extra url parameters will actually be necessary (and the links will no longer work indefinitely)
By the way for anyone who doesn’t know, the ? only appears once in the url. Successive question marks are instead denoted by &
