Tinfoil Hat Linux (THL) is a compact security-focused Linux distribution designed for high security developed by The Shmoo Group. The first version (1.000) was released in February 2002. It appears to be a low priority project as of 2013. Its image files and source are available in gzip format. THL can be used on almost any modern PC, as it requires an Intel 80386 or better computer, with at least 8 MB of RAM. The distribution fits on a single HD floppy. The small footprint provides additional benefits beyond making the system easy to understand and verify- the computer need not even have a hard drive, making it easier to "sanitize" the computer after use.
