Snow Cheat Sheet (DRAFT) by

This cheat sheet will help you with the fundamentals to using the Snow stenography tool.

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Options

-C
Compress the data if concea­ling, or uncompress it if extrac­ting.
-Q
Quiet mode. If not set, the program reports statistics such as compre­ssion percen­tages and amount of available storage space used.
-S
Report on the approx­imate amount of space available for hidden message in the text file. Line length is taken into account, but other options are ignored.
-p encryp­tio­n-key
If this is set, the data will be encrypted with this password during concea­lment, or decrypted during extrac­tion.
-l line-l­ength
When appending whites­pace, snow will always produce lines shorter than this value. By default it is set to 80.
-f messag­e-file
The contents of this file will be concealed in the input text file.
-m message
The contents of this string will be concealed in the input text file. Note that, unless a newline is somehow included in the string, a newline will not be printed when the message is extracted.
