Suppose we have a lowercase alphabet string called text. The Atbash cipher is a simple substitution cipher that relies on transposing all the letters in the alphabet such that the resulting alphabet is backwards. Atbash is its own inverse, so you do not need separate Encode() and Decode() methods: Atbash(b) = y; Atbash(y) = b for example. Instead of shifting a letter to the right, it replaces the first letter of the Hebrew alphabet (aleph) with the last letter (tav) then the second letter (beth) for the second to last letter (shin), etc. The Atbash cipher is essentially a substitution cipher with a fixed key, if you know the cipher is Atbash,then no additional information is needed to decrypt the message. Here is the English version of the atbash cipher, using the same right-to-left ordering (since the code transposition does not depend on how the cipher is displayed here). How to encrypt using the Atbash cipher Atbash encryption uses a substitution alphabet and its reciprocal, a combination of the normal alphabet and its reverse alphabet (mirrored). Episode 20 is trickier as it uses a combined cipher, requiring you first to use the A1Z26 cipher, then the Atbash cipher, and finally the Caesar cipher … As the first cipher, it offered close to zero security as it followed a very simple substitution method. 14 0 obj <> endobj An Atbash cipher for the Latin alphabet would be as follows: It was originally used to encode the Hebrew alphabets but it can be modified to encode any alphabet. ��3�F���޿Y�>�d��'d�q�]��W���}{SE5�2�~Uv�~��{�Z�G �M�����\�$6H�4���8�, �� Sunday: 11:00AM–3:00PM, Jewish High School Math League - Theme by Grace Themes.
