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?
