Answers to Questions

How to encrypt using Atbash cipher

Encryption uses a substitution alphabet and its reciprocal: its reverse alphabet (mirrored).

Example: Consider ABCDEFGHIJKLMNOPQRSTUVWXYZ and its reverse: ZYXWVUTSRQPONMLKJIHGFEDCBA

NormalABCDEFGHIJKLMNOPQRSTUVWXYZ
ReverseZYXWVUTSRQPONMLKJIHGFEDCBA

Encryption consists in replacing lettershref from the first with letters from the other one, with is equivalent to replace the first letter of the alphabet with the last one, the second one with the penultimate etc.

Example: DCODE becomes WXLWV

How to decrypt Atbash cipher

Decryption is identical to encryption because of the reversible alphabet

Example: ZGYZHS is decrypted ATBASH

How to recognize an Atbash ciphertext?

An Atbash ciphertext has a coincidence indexhref similar to an unencrypted text.

If the encryption used the classical latin alphabet, letters V,G,R,L,M appears the most frequently.
