The mechanism works by submitting the database master seed as a challenge to the YubiKey which replies with a HMAC-SHA1 cryptographic hash. The resultant hash is then hashed with the other keys (password, keyfile) to generate the final key used to encrypt the database. <\/i><\/p><\/blockquote>\n<p><b>How to Install KeePassX 2.0 with YubiKey support:<\/b><\/p>\n<p>Open terminal from Unity Dash, App Launcher, or via Ctrl+Alt+T shortcut key.
