Nitrokey is a hardware security module (HSM) with USB interface, which keeps the private OpenPGP keys or private X.509v3 in a secure environment. All cryptographic operation with private keys are computed on the HSM. The private key will never leave the secured environment.

Additional offers Nitrokey 8 slots for one-time-passwords (HOTP and TOTP) for secure login on web-services and 8 slots for static password. All passwords are stored encrypted on the USB device.

The most advanced version of Nitrokey is “Nitrokey storage”. This version offers additional Veracrypt encrypted storage up to 64 GB. Encryption/decryption to access the storage is done in transparent way, installation of Veracrypt is not required.

For more detailed information you may have a look at the website: https://www.nitrokey.com

To use the advanced features like HOTP/TOTP, password safe and encrypted storage the software Nitrokey-App is required. May be, it would be a nice feature, to have this software pre-installed in TAILS to make it easy for security affine users to use the Nitrokey HSMs out of the box with TAILS.

he Nitrokey-App is part of Debian 9.0 and can be installed from Debian main repository.
