ZeroShadow: a military-grade encrypted notepad that redefines personal data security. Unlike conventional notepads, ZeroShadow is an innovative, self-contained security solution that ensures your information remains entirely private and protected.

Self-Executing Encryption

With ZeroShadow, every document you create transforms into a fully autonomous, self-executing, encrypted application. There's no need for installation or any external software; open notepad app of choice, create your file, and you're set.

When you save a file in ZeroShadow:

    ● Your text is encrypted with AES-256-CBC
    ● HMAC-SHA256 authentication tag is computed
    ● The encrypted data is appended to a copy of the ZeroShadow executable
    ● The result is a single .exe file containing both the decryption engine and your encrypted data
    ● Double-clicking this file runs the embedded decryption engine and prompts for your password
    ● Upon successful authentication, HMAC is verified before decryption
    ● Your data is decrypted in memory and displayed
    ● Closing the window automatically exits—no temp files, no traces
