1 | # Binary Whitespace Encoder and Decoder
2 | This project uses zero-width whitespaces and binary encoding to hide String values, the process consists of converting the String to a binary value and then mapping the 0's and 1's into specified zero-width whitespaces, which results in a zero-width string which contains all the information.
3 | 
4 | This project is merely a proof of concept to some friends.
