Abstract
Crypto Tools Library is a set of reconfigurable cryptosystems and cryptographic primitives developed based on RVC-CAL. The main goal is to offer an easy-to-use library for both the cryptography and multimedia communities. For cryptography community, it can be used as a fast prototyping platform for creating cryptosystems and testing their performance. For multimedia community, the CTL can be used: 1) to demonstrate that RVC-CAL is a fast prototyping language capable of developing more applications beyond video codecs; 2) to lay the foundation of developing reconfigurable multimedia security systems by combining VTL and CTL. The CTL is open-source available for downloading at the following SVN site: https://orc-apps.svn.sourceforge.net/svnroot/orc-apps/trunk/Crypto
