The secure key for your digital life. Encrypts your emails, files, and server access. Protects against hackers and espionage – private and professional.

The cryptographic key is securely stored in the Nitrokey and is thereby protected against loss, theft and malware. With strong hardware encryption, made reliable thanks to open source, quality made in Germany.

For Anybody – Protection Against Mass Surveillance and Hacker

• Encrypt Emails
  Encrypt your emails with GnuPG, OpenPGP, S/MIME, Thunderbird or Outlook. Your private keys are securely stored in the Nitrokey and cannot be exported or stolen.

For Businesses, Chancelleries and the Self-Employed – Protect Sensitive Data

• Protect Your Data Against Espionage
  Encrypt field workers’ entire hard drives by means of TrueCrypt/VeraCrypt or individual files by means of GnuPG. The private keys are thereby securely stored in the Nitrokey.
• Desktop Login
  Log in easily at your local computer desktop with the Nitrokey.

For IT Administrators and Security Experts – Protect Critical Infrastructure

• Securely Administrating Servers With SSH
  Securely store your SSH keys in the Nitrokey at all times. Your key is PIN-protected and cannot be exported or stolen from the Nitrokey. This means that you can bypass the insecure and tedious process of synchronizing key files between client systems.
• Internet of Things (IoT) and Protecting Your own Products
  Protect your own hardware products using Nitrokey integration. Ideal for remote maintenance and for ensuring product authenticity.
