ROT47 Encode/Decode, ROT47 Character Substitution Cipher with API

rot47.net

This page provides a Javascript online web-based ROT47 Encoder/Decoder. The ROT47 (Caesar cipher by 47 chars) is a simple character substitution cipher that replaces a character within the ASCII range [33, 126] with the character 47 character after it (rotation) in the ASCII table. It is an invertible algorithm i.e. applying the same algorithm to the input twice will get the origin text. This page also provides LUA function/cipher implementation for many popular programming languages.
