YAPET is a curses based password encryption tool using the Blowfish encryption algorithm to store password records encrypted on disk. Its primary aim is to provide a safe way to store passwords in a file on disk while having a small footprint, and compiling and running under today's most popular Unixes, such as Sun™ Solaris™, FreeBSD®, and Linux.

If you are looking for a fully fledged password encryption tool having a graphical user interface, I recommend you start with revelation (http://oss.codepoet.no/revelation/). YAPET is text based and less feature rich in comparison to revelation.

Using several different Unixes, I wanted to have a single application running on all Unixes for storing my passwords in a secure manner and running easily over a secure shell connection.

YAPET builds and runs on following platforms:

If you want to use YAPET under Cygwin, you may want to read the README.Cygwin file.

YAPET features:

YAPET uses a configure script for configuring the build process. Refer to the INSTALL file in the source tarball yapet-0.4.tar.gz.

YAPET is kept simple. You should not find it difficult to use. The user interface has some quirks, though.

See the manual page yapet(1) after installing YAPET for a minimal usage guide.

Refer to the DESIGN file which comes along with the source tarball in order to get an idea of the design of YAPET.

Although several precautions were taken to avoid having any passwords stored clear text in memory, there were occassions when core files contained the master password. This means that it is possible, though not likely, for a malicious user to get hold of one or more passwords while YAPET is running.
