Software for a separate trusted hardware device ("hardware security module") which essentially acts just like Keepass and only serves the function of storing secrets.
If you use Keepass on your PC and your PC gets compromised by a virus or a hacker, it's game over. But if you use a separate device for storing secrets, your PC compromise does not expose your secrets. This software only exposes your secret when you physically press a button on the device - and only exposes one secret per push acknowledge.
- Architecture summary
- Comparison to alternatives
- All documentation - everything you seek is probably here. The above links were just some of the most important links to this documentation site.
- No cloud
- Physical acknowledgement to expose a password by pressing a button on a U2F key (YubiKey for example), so a hacker would need local, physical, access to steal your secrets.
- Supported secrets:
- Passwords
- OTP tokens (Google Authenticator)
- SSH keys (via SSH agent protocol)
- Keylists ("printed OTP list")
- Freetext (any text content is treated as secret data)
- Create, view and list secrets in a folder hierarchy.
- Export database to Keepass format (for viewing in mobile devices when traveling etc.)
- Import data from Keepass format
I'm using Raspberry Zero W with wooden case.
It doesn't matter much which hardware you use, as long as you don't run anything else on that system - to minimize the attack surface. For such a light use Raspberry Pi is economical, although this project runs across processor architectures and operating systems because Golang is so awesome. :)
Click the "Download" badge at top of this readme and locate the binary for your OS/arch combo:
- For Raspberry Pi, download
pism_linux-arm - For Linux PC, download
pism_linux-amd64
Note: don't worry about public.tar.gz - it's downloaded automatically if it doesn't exist.
Rename the downloaded binary to pism.
Pro-tip: you can download this directly to your Pi from command line:
$ mkdir passitron/
$ cd passitron
$ curl --fail --location -o pism <url to pism_linux-arm from Bintray>
# mark the binary as executable
$ chmod +x pism
Installation & running:
$ ./pism server init-config admin yourpassword
$ ./pism server install
Wrote unit file to /etc/systemd/system/passitron.service
Run to enable on boot & to start now:
$ systemctl enable passitron
$ systemctl start passitron
$ systemctl status passitron
Looks good. You should now be able to access the web interface at http://<ip of your pi>.
How to build & develop (with Turbo Bob, our build tool). It's easy and simple!
