Description:
steganography using ASCII files
This utility can conceal messages in ASCII text by appending whitespace to the end of lines. Because spaces and tabs are generally not visible in text viewers, the message is effectively hidden from casual observers. And if the built-in encryption is used, the message cannot be read even if it is detected. . About the name: locating trailing whitespace in text is like finding a polar bear in a snowstorm. And it uses the ICE encryption algorithm, so the name is thematically consistent.
