tomb - 2.9+dfsg1-2 main

Tomb is a free and easy to operate desktop application for fairly strong
encryption of personal files. A tomb is like a locked folder that can be
transported and hidden in filesystems; its keys are password protected and can
be kept separate, for instance keeping the tomb file in your computer's
harddisk and the key file on a USB stick.
.
Tomb relies on dm-crypt (and cryptsetup) as an encryption backend using the
aes-xts-plain64 cypher.
