The realcrypt application in the RPM Fusion repo is an encryption application based on truecrypt, freely available at http://www.truecrypt.org/. It differs from truecrypt in only the following ways:
The name truecrypt is changed to realcrypt throughout the application, as requested by the truecrypt License:
All original graphics are replaced with entirely original new ones, as requested by the truecrypt License:
A small patch allows alternative optimization flags to those specified in the original buildsystem to be used during compilation, and the binary package is compiled using Fedora's standard optimization flags.
Additional support scripts and configuration files are included that allow the application to run through consolehelper. This simply means that you can attempt to run the application as a regular user, and it will prompt you for the administrator password and then launch the application with administrator privileges.
A menu entry for the application is added
