Atbash & Affine Ciphers
Explore Hebrew Atbash and the mathematical affine cipher.
Welcome
In this lesson we study Atbash, a Hebrew mirror cipher, and the Affine cipher, which applies a linear mathematical transformation to each letter.
Atbash Cipher
Atbash mirrors the alphabet: A↔Z, B↔Y, C↔X, ... It originates in Hebrew scripture (~600 BCE). The word 'Sheshakh' in Jeremiah is Atbash for 'Babel'.
