Need to install all dependencies
yum install "compat-libstdc++-33.i686" "compat-libstdc++-33.x86_64"; yum install zlib-devel.i686; yum install libjpeg-turbo-devel.i686; rpm -ivh "http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm"; yum install libmcrypt-devel; yum install mhash.i686; yum install "libmcrypt.i686";
root@server [/tmp]# rpm -ivh steghide-0.5.1-1.i386.rpm?download Preparing... ########################################### [100%] 1:steghide ########################################### [100%]
now you can use it for example
steghide embed -cf in.jpg -ef out.jpg -p password
- in.jpg is file where we want to add hidden data
- out.jpg is ready file after add is completed
- password is pass to encrypt data
