| | Cryptography History : 500 - 600 B.C. ATBASH Cipher (Site not responding. Last check: ) |
 | | The ATBASH cipher is a Hebrew code which substitutes the first letter of the alphabet for the last and the second letter for the second last, and so on. |
 | | In the case of the Atbash cipher, the first letter of the alphabet is substituted for the last, the second for the second last and so on." I.e., for us in English the letter A becomes "Z", the letter "B" becomes "Y", the letter C becomes X, and so on. |
 | | ATBASH gets it's name from the fact that in the cipher, A becomes tav(the last), B becomes shin (one before last), and so on, hence ATBSh - ATBASH. |
