About this atbash cipher

Atbash replaces each letter with its mirror in the alphabet: A with Z, B with Y, C with X. It began as a Hebrew cipher (aleph-tav, beth-shin, hence the name) and appears in the Book of Jeremiah. Because the mapping is its own inverse, running it again restores the text.

Common questions
