yesCoder is a program to hide data in ASCII text files. It can also be used to format ASCII text files. Hiding data means that the data is coded into an ASCII text file. The idea is that this ASCII text file (a poem, a story, technical documentation, etc.) looks so innocent that no one would guess that therein is some interesting data. If you have the need to hide some data like passwords, accounts, phone numbers, etc., so that no one can find it, yesCoder is the right tool for you. You even may send this coded data to other persons via email.
SNOW is a utility for concealing messages in ASCII text by appending whitespace to the end of lines. Because spaces and tabs are generally not visible in text viewers, messages concealed with whitespace are effectively hidden from casual observers. If SNOW's built-in encryption is used, the message cannot be read even if it is detected. SNOW exploits the Steganographic Nature Of Whitespace, similar to finding a polar bear in a snowstorm; hence the name.
