&lt;br /&gt;
'''BlindSide Cryptographic Tool''' by John Collomosse is a command-line steganography tool that hides information in BMP files with optional encryption.&lt;br /&gt;
&lt;br /&gt;
Images can typically contain 50k of secret data and you can add many (small) files into one single image. &lt;br /&gt;
&lt;br /&gt;
Blindside analyses the color differentials in the image, and will only alter pixels that it knows will not be noticeable to the human eye. The downside is that each image has its own 'capacity' dependent on colour patterns within it - but the upside is that any data you scramble with Blindside will most definitely be invisible to the human eye.&lt;br /&gt;
&lt;br /&gt;
Blindside is more resilient that most when it comes to image tampering - since not every pixel is critical to the data storage algorithms, usually about 50% are redundant.&lt;br /&gt;
&lt;br /&gt;
Source code plus compiled binaries for Win32, Linux, AIX, HPUX and Solaris are available.&lt;br /&gt;
