cipher

Here are 132 public repositories matching this topic...

This is a Caesar cipher for both encoding and decoding. The key is an integer from 1 to 25. This cipher rotates the letters of the alphabet (A to Z). The encoding replaces each letter with the 1st to 25th next letter in the alphabet (wrapping Z to A). So key 2 encrypts "HI" to "JK", but key 20 encrypts "HI" to "BC".

A program that encrypts a given text in such a way that, instead of letters, the program outputs the atomic number of the element which chemical symbol corresponds to the encrypted letters, ignoring their case. The space between letters should be replaced with an asterisk, and the space between words should be replaced with two asterisks.
