    Software

    stegocurve

    Description

    The primary goal of stegocurve is to provide a simple tool for plotting curve from code based steganography. This is a standalone ANSI-C tool. It can be used for Unix and Windows computers. Any feedback is appreciated. stegocurve is under the GPLv3 licence.

    All remarks or suggestions are useful, let me know by e-mail.
