+OpenStego is a tool implemented in Java for generic steganography,
+with support for password-based encryption of the data.
+
+Features:
+
+ - OpenStego is written in pure Java and should run on all platforms
+   supported by java. It has been tested on MS Windows and Linux,
+   but should not have any problem on other platforms too. Please
+   report bugs if you find any.
+ - It supports password-based encryption of data for additional
+   layer of security. DES algorithm is used for data encryption,
+   along with MD5 hashing to derive the DES key from the password
+   provided.
+ - It uses a plugin based architecture, where various plugins can
+   be created for different kind of Steganographic algorithms.
+   Currently, it supports two plugins - LSB (Using Least Significant
+   Bit of Image Pixels) and RandomLSB (Randomized LSB), but new
+   plugins can be created for other algorithms like DCT, FFT, etc.
+   Plugins can also be easily added for other type of cover files
+   like Audio files.
+ - LSB plugins support only 24 bpp images. Support for additional
+   image formats (like BMP, TIF, etc.) could be added by installing
+   Java Advanced Imaging (JAI).
+ - LSB plugins also support generation of random images containing
+   noise to be used as cover file. The size of the generated random
+   image is the minimum possible size required to embed the given data.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
