- rplnt 15y agoI don't think I follow. What is the question? (To get inverse password you simply reverse the case on all letters.)
- pazimzadeh 15y agoI mean that while facebook prompts you for a password in a single field, if you enter "passWORD" the true value of your password is both "passWORD" and "PASSword", but there's no way to express that idea in the english language. If someone asked you what your password was, what would you say if you wanted to be completely accurate? It's just a dumb philosophical thought I had.
- shawabawa 15y agoI guess the original password is stored as a hash in the DB normally, then when someone logs it it hashes what they entered, what they entered with the first char lowercased, and what they entered with all cases inverted, and see if any of the hashes match.
