Encryption, decryption, and cracking. Thanks to this exploration of the Caesar Cipher, we now understand the three key aspects of data encryption: Encryption: scrambling the data according to a secret key (in this case, the alphabet shift). Decryption: recovering the original data from scrambled data by using the secret key.A Caesar Cipher is a special kind of cryptogram, in which each letter is simply shifted a number of positions in the alphabet. It can easily be solved with the Caesar Cipher Tool. A ROT13 Cipher is similar to a Caesar Cipher, but with a fixed shift of 13 letters. It can easily be solved with the ROT13 Tool. Sample Cryptogram The shift is named a “ROT,” which stands for “rotation.”. For example, with a ROT1 shift A becomes B, B becomes C, and so on. With a ROT13 shift, on the other hand, A becomes N, B becomes O, C becomes P, etc. To decode a message sent using the Caesar Shift cipher the person must be aware what shift has been used.
