A custom module which encrypts user input using a Caesar cipher, also known as Caesar's cipher, the shift cipher, Caesar's code, or Caesar shift. 12.09.2016
This is a simple web app for users to try out a custom module which encrypts user input using a Caesar Cipher. This is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions (either right or left) down the alphabet. Any spaces or punctuation in the input phrase are ignored and reproduced in the final result without being shifted.
| Behavior | Input Shift Value | Input Shift Direction | Input Phrase | Encrypted Output |
|---|---|---|---|---|
| Shift right | 1 | right | a | b |
| Shift left | 1 | left | b | a |
| Shift right with wrap-around | 1 | right | z | a |
| Shift left with wrap-around | 1 | left | a | z |
| Shift right 'through' alphabet one or more times | 55 | right | a | d |
| Shift left 'through' alphabet one or more times | 55 | left | a | x |
| Enter multi-word phrase with punctuation | 25 | right | E.T. phone home. | d.s. ognmd gnld. |
