rustencrypter-cli

An encryption cli tool for directories and files written purely in Rust. Uses AES-GCM with 128 bit encryption.

Installation

git clone https://github.com/Ayuei/rustencrypter.git
cargo install --path rustencrypter

Usage

./rustencrypter <input file> <--[e]ncrypt|--[d]ecrypt> --[k]ey <key file>

Note encryption and decryption will overwrite the source file, this will be altered in future with a flag

You can only do a single encrypt or decrypt operation per call

Features

• Encrypt a file
• Encrypt all files in a given directory
• Automatic key generation (creates "key" in calling/working directory) or requested directory/file
• User can specify specific key file (16 bit)
• Fresh nonce every encryption
• Encryption/decryption chaining

Neat things

You can chain multiple encryptions and decryptions symmetrically for added security.

./rustencrypter file -e
./rustencrypter file -e
./rustencrypter file -d
./rustencrypter file -d

TODOs

• Release compiled binaries for all platforms
• Add an optional flag for an output file
• Add authentication for tamper detection (HMAC)
• Add support for embedded encryption and decryption chaining
• Refactor for speed using callbacks
• Fix some race conditions in the test cases
• Multi-threads or Async for directory encryption/decryption
• Add python bindings (personal project)

Feel to do any pull requests or let me know about any issues.
