Rust Encryptor UI

Rust Encryptor UI is a small cross‑platform desktop application for encrypting and decrypting files with a passphrase. It is built with the eframe GUI framework and uses modern cryptography to protect your data.

Features

• File encryption/decryption via a simple graphical interface.
• Uses AES‑256‑GCM for authenticated encryption and Argon2 for password‑based key derivation.
• Random 16‑byte salt and 12‑byte nonce are generated for each encryption run.
• Output format: MAGIC | VERSION | SALT | NONCE | CIPHERTEXT.
• Passwords are wiped from memory after each operation.

Building

1. Install the Rust toolchain.

2. Build and run the application:

   cd rust-enc-ui
   cargo run --release

The release build will produce a native executable and launch the GUI.

Usage

1. Choose whether to Encrypt or Decrypt.
2. Select the input and output files.
3. Enter the password (and confirmation when encrypting).
4. Click the action button and wait for the status message.

File format

Encrypted files are written with a small header so the app can verify integrity during decryption:

[0..3]  "RENC" magic bytes
[4]     version byte
[5..20] salt (16 bytes)
[21..32] nonce (12 bytes)
[33..]  ciphertext

Development

Run the test build to verify the project compiles:

cargo test
