Atbash cipher
Atbash is a simple
substitution cipher in
Hebrew. It consists of substituting
aleph (the first letter) for
tav (the last),
beth (the second) for
shin (one before last), and so on, reversing the
alphabet. A couple of words in the
Book of Jeremiah,
Leb Kamai and
Sheshakh, are atbash for
Kasdim (
Chaldeans) and
Babel respectively, probably written thus.
