AirCypher

Security known only to a few

About Us

Cybersecurity Expert

AirCypher is a Slovenian technology company developing advanced solutions for private and secure communication.
We specialize in creating fully offline encrypted messaging devices that require no internet, cellular network, or satellite connection.

Our flagship device, AirCypher, converts messages into encrypted QR codes that can only be read by a dedicated receiver – no servers, no logs, no interception.

We believe that privacy is a fundamental human right, which is why we build tools that give users back control over their data. Our mission is to enable secure communication for everyone, anywhere.

Step 1: Select Strong Password

Begin by typing a secure, complex password into the designated field. This password acts as your encryption key—so make sure to use a mix of uppercase and lowercase letters, numbers, and special characters. Remember this password, as you will need it later to decrypt your information.

Step 2: Enter the Text

In the next input area, type the plaintext message, sensitive data that you want to protect. This is the exact information that will be secured by the encryption process.

Step 3: Encrypt

Press the Encrypt button. The device’s internal processor will automatically perform the cryptographic algorithm on your text using your password. Upon completion, the device will display a QR code on its screen—this QR code contains your fully encrypted data, ready to be scanned and shared
