snow is a command-line tool designed specifically for hiding information within text. Its approach is clever: it encodes content using whitespace characters such as spaces and tabs that are nearly invisible to the naked eye. Open the file and the text looks unchanged, the layout appears normal, yet another layer of information has been quietly embedded inside. For those who need to pass messages without drawing attention or who are interested in steganography, this tool offers a simple and direct method. It suits users accustomed to working in the terminal, requires no graphical interface, and can embed and extract data in just a few commands. Since it modifies whitespace characters, the visible content of the original text remains essentially unaffected, which in certain scenarios makes it more discreet than conventional encryption.

snow is a command-line tool based on whitespace steganography, used to hide messages in the spaces and tabs within text. It addresses the need to transmit hidden content without drawing attention—what appears to be ordinary plain text is actually text in which the arrangement of whitespace characters encodes additional information. It suits technical users interested in information hiding and steganography, or scenarios that require discreetly embedding markers in text files. As a command-line tool, it is aimed more at users with some hands-on ability rather than ordinary office software users. Before use, it is best to understand the basic principles of steganography, and to note that this kind of technology should not be used for improper purposes.
