Signet is a free and open source software and open hardware USB storage and encryption device that also acts as a password manager. Signet identifies as a USB keyboard allowing it to type your data when you need it.

Signet hardware will soon be available for purchase.

The original development was done by Nth Dimension in 2017 as a crowd funded project on Crowdsupply.

Since then it has been revived by Adam at Hax0rbana, who is the current developer/maintiner of the hardware, software and firmware as well as the primary producer of the hardware.
