TrueCrypt is free open-source disk encryption software for Windows 7/Vista/XP, Mac OS X, and Linux. Since version 6.1a of TrueCrypt, a number of header files from RSA Laboratories are required during the compilation. I've separated the installation of these into a separate package called cryptoki rather than have this script extract a separate, isolated archive. Thus, to build this version of TrueCrypt, you also need cryptoki, and to run Truecrypt you need wxGTK. Both are available at SlackBuilds.org. This script does not create the static GUI build seen elsewhere (see above for required runtime dependency of wxGTK or similar). NOTE: There is no direct link to the TrueCrypt source archive, as such, it must be downloaded manually from within a web browser.
