To anyone getting hung up on the -Heeeer-s Johnny!- Challenge... in the video John reveals the password as -kissme- I already had some knowledge of using John and I did my own thing a lil ahead of him... my cracked pass came out to be -hellokitty- after being stumped on what he was showing us va what my hash crack showed it seems like between the filming of this video and when I seen it that they changed the flag on us... my password took and got the flag which was also accepted... so don-t get frustrated like I did when it wasn-t coming out the same

On the RSA mad libs, how can I decrypt the flag without using python? Everytime I try decoding the flag with python it doesn't work, and using online decoders are giving me the original plain text.

That cipher is the top cipher family?
From the first one -Rix- is -The- easily like that can crack: x = e, R = T, i = h.
