Tomb, the Crypto Undertaker 2.4

Tomb is a system to make strong encryption easy for everyday use. A tomb is like a locked folder that can be safely transported and hidden in a filesystem. Its keys can be kept separate; for example, you can keep the tomb on your computer and its key on a USB stick. Tomb is written in code that is easy to review and links shared components: it consists of a ZShell script and desktop integration apps; it uses standard GNU tools and the crypto API of the Linux kernel (dm-crypt) via cryptsetup.
