Illustration: How Nitrokey works

How Nitrokey works

Protect emails, files, hard drives, server certificates and online accounts using cryptography. Your secret keys are always stored securely in the Nitrokey hardware and can't be stolen. The device is PIN-protected and is secured against hardware attacks. Backups protect against loss.

Nitrokey is better:

  • High Security

    Your secret keys are stored in the tamper-resistant and PIN-protected device and are secured against computer viruses, loss and theft. RSA keys of up to 4096 bit and AES-256 are supported.

  • Independent Security Assessment

    The auditing company Cure53 performed an intensive security review of the Nitrokey Storage. The security expert summarize their final result with "Nitrokey is capable of functioning properly and securely". The complete final report can be downloaded publicly (FirmwareHardware).

  • Open Source

    Both hardware and software are open-source, free software and allow independent security reviews. Customisable, no vendor lock-in, no security via obfuscation, no hidden security issues!

  • No Backdoors - No NSA

    Installed firmware can be exported and verified, preventing attackers from inserting backdoors into products during shipping. Nitrokey is open-source and free of backdoors. Secret keys are generated only by you and we have no access to your private information.

  • Plausible Deniability

    The only hardware solution with hidden encrypted storage. This allows you to plausibly deny the existence of encrypted data, for example during border controls.

  • Easy Integration

    Nitrokey uses open interfaces to enable its easy integration with your personal requirements. Custom solution can be provided on request.

  • Better Than Software

    The Nitrokey hardware functions independently of any operating systems and protects your secret keys against theft, loss, user mistakes and computer viruses.

News

  • During our crowdfunding campaign last year we estimated the shipping date of the Nitrokey Storage would be 2 May 2016. As we have previously mentioned, the time-critical aspect of the project is the development of the plastic casing. We have already made three revisions to the design of the casing and this week we received the latest sample of the casing. Unfortunately the casing isn't ready yet which is why we have had to postpone the release date of the Nitrokey Storage to June.
