ROT13 Encoder/Decoder

ROT-13 Decoder/Encoder

• Initially written for fun for a CTF
• Can take a string and encode/decode using ROT13

From Wikipedia:

Applying ROT13 to a piece of text merely requires examining its alphabetic characters and replacing each one by the letter 13 places further along in the alphabet, wrapping back to the beginning if necessary. A becomes N, B becomes O, and so on up to M, which becomes Z, then the sequence continues at the beginning of the alphabet: N becomes A, O becomes B, and so on to Z, which becomes M. Only those letters which occur in the English alphabet are affected; numbers, symbols, whitespace, and all other characters are left unchanged. Because there are 26 letters in the English alphabet and 26 = 2 × 13, the ROT13 function is its own inverse:

To-Do

• Write simple script for encoding and decoding ROT13 strings
• Write to accept string as an argument and return the desired string
• Debug
