  • Made in Germany

    Nitrokey is developed and produced in Germany, primarily in Berlin. For the sake of higher quality and security, we do not use cheap overseas manufacturing.

  • Independent Security Assessment

    The auditing company Cure53 performed an intensive security review of the Nitrokey Storage. The security experts summarize their results with "Nitrokey is capable of functioning properly and securely" (see final report available here FirmwareHardware).

  • Complete USB plug

    Unlike some competitors, Nitrokey contains a complete and standard compliant USB plug. This ensures thousands of insertions without connectivity 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 and open drivers 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, phishing, brute-force attacks, computer viruses and other malware.

  • Sustainability

    The sustainable development and production of Nitrokeys contributes to a sustainable environment and society.

News

  • Time flies. This week five years ago, Nitrokey was incorporated. Although our roots reach back to 2008 when the non-profit open source project "Crypto Stick" was started, 2015 marked the year of entering the business world. The mission: building the best open source hardware security keys on the market, enabling data encryption, user authentication and key management.

  • Do you think your computer hardware is secure? Can you rule out that in your absence no one has manipulated your computer? In a world, where most users do not have any real control over their hardware and have to blindly trust the security promises of vendors, NitroPad unlocks a refreshingly new security experience. NitroPad X230 is significantly more secure than normal computers.

  • We are happy to introduce the new Nitrokey FIDO2! The device can be ordered now and will be delivered within the next days. Nitrokey FIDO2 convinces by easy handling, two-factor authentication (2FA) and it can be used for passwordless login instead of a password. This brings us one step closer to our motto "secure your digital life".
