1  # OTPninja File Encryption Tool
 2  
 3  ## Overview
 4  
 5  OTPninja is a professional-grade file encryption and decryption tool built in Rust, leveraging the **One-Time Pad (OTP)** encryption technique. This tool provides a secure and efficient way to encrypt and decrypt files using XOR operations with a randomly generated OTP. The OTP ensures perfect secrecy when used correctly, making this tool ideal for scenarios where data confidentiality is paramount.
 6  
 7  The tool is designed with simplicity and security in mind, offering the following features:
 8  - **OTP Generation**: Generate a cryptographically secure OTP tailored to the size of your input file.
 9  - **File Encryption**: Encrypt files using the generated OTP.
10  - **File Decryption**: Decrypt files using the same OTP, ensuring data integrity and confidentiality.
11  - **Secure Memory Handling**: Utilizes the `zeroize` crate to securely handle sensitive data in memory, preventing residual data exposure.

32  ## Features
33  
34  - **Cryptographically Secure OTP Generation**: Uses `rand::rngs::OsRng` to generate high-quality random bytes for the OTP.
35  - **Perfect Secrecy**: Ensures that the encrypted data cannot be decrypted without the exact OTP.
36  - **Zeroization of Sensitive Data**: Automatically clears sensitive data (e.g., OTP) from memory after use to prevent accidental exposure.
37  - **Cross-Platform Compatibility**: Built in Rust, ensuring portability and performance across different operating systems.
38  - **User-Friendly CLI Interface**: Provides an intuitive command-line interface for generating OTPs, encrypting, and decrypting files.

83  An LXMF address is a unique identifier used for secure communication over the LXMF protocol, enabling users to send and receive encrypted messages. I suggest using the Sideband app or Nomad Network for this purpose.
