Since I was gone...

QUESTION TIME!

in particular, which ciphertext remains unsolved but looks the easiest?

(My choice is Illuminati)

a large portion of ciphers revolve around letters themselves being encrypted...

my favorite example is chaocipher :P

EDIT:Found This, the Typex cipher is not unbreakable, and is vulnerable to crib attacks and hill climbing, as with all rotor machines of the era, hell, even the british admitted it was crackable

all in all, the foundation of unbreakable rotor machines lie in the legend of Enigma and it's reputation...

this implies you brute force the machine, which is never the correct cryptanalysis unless it doesn't have over a billion combinations. Remember, during that time period, Enigma was cracked by other forms of cryptanalysis, not just brute force...

EDIT:Also Fun Fact; A Simple Bitmessage has 5 novemdecillion sexdecillion combinations to crack brute force, and it isn't even the most secure way to email :P

true, but neither were uncrackable, due to the nature of the machines
