What is "keepassx"

KeePassX started as a Linux port of KeePass , which was at that time an open source but Windows-only password manager. Both are now cross platform, with KeePassX using Qt libraries and recent versions of KeePass using .NET / Mono.

It is built using version 4.8 of the Qt libraries, making it a multi-platform application, which can be run on Linux, Windows, and Mac OS X.

KeePassX uses the KeePass 2 (.kdbx) password database format as the native format. It can also import (and convert) the older KeePass 1 (.kdb) databases.
