一个将任意文件隐藏到一张图片里的命令工具。

Install

brew install stegify

Usage

As a command line tool

$ stegify -op encode -carrier <file-name> -data <file-name> -result <file-name>
$ stegify -op decode -carrier <file-name> -result <file-name>

When encoding, the file with name given to flag -data is hidden inside the file with name given to flag -carrier and the resulting file is saved in new file in the current working directory under the name given to flag -result. The file extension of result file is inherited from the carrier file and must not be specified explicitly in the -result flag.

When decoding, given a file name of a carrier file with previously encoded data in it, the data is extracted and saved in new file in the current working directory under the name given to flag -result. The result file won't have any file extension and therefore it should be specified explicitly in -result flag.

In both cases the flag -result could be omitted and it will be used the default file name: result

Programmatically in your code

stegify can be used programmatically too and it provides easy to use functions working with file names or raw Readers and Writers. You can visit godoc under steg package for details.
