The atbash cipher (or athbash, under which name Web3 defines it) is a Hebrew substitution cipher which replaces the first letter of the Hebrew alphabet (aleph, X) but the last (tav, n) which is replaced by the first (aleph, x). Jan Anderson described it in "Fledge Ledge Edge" (WW 8. 1997-229). Naturally, the idea can be applied to our alphabet; following the precedent set by "atbash", I name it the azby cipher.
