Cryptograms and interactive news for amateur and professional cryptanalysts
This site will be moving to SqueamishOssifrageSociety.com in the near future. The site you are currently visiting is being dismantled and is no longer supported.
Welcome
I hope you enjoy breaking these cryptograms as much as I enjoyed making them.

Want to break real codes? If you're a U.S. citizen, you might consider working for the National Security Agency. (If you think they're all a bunch of old guys in dark suits without personalities, think again!)

Thanks for stopping by, John! Anyone who's seen your work on other crypto sites knows you're capable of doing the much tougher puzzles, so I look forward to seeing you take a shot at some of the more challenging ones, too.
For those who are new to cryptograms, note that the key to the atbash cipher is:
p: ABCDEFGHIJKLMNOPQRSTUVWXYZ
c: ZYXWVUTSRQPONMLKJIHGFEDCBA
In other words, we can say that plaintext A equals ciphertext Z and vice versa:
A=Z
B=Y
C=X
D=W
E=V
F=U
G=T
H=S
I=R
J=Q
K=P
L=O
M=N
I found this cipher very interesting! It prompted me to do more research on "atbash."
