Warning: This project is for educational purposes only and should not be used for real-world encryption or decryption of sensitive data. It is still a work in progress and should not be used for any real-world applications.
This is a Rust project that provides functionality for file encryption and decryption using AES (Advanced Encryption Standard) with a 256-bit key and RSA (Rivest–Shamir–Adleman) with a 2048-bit key. It also uses a hash function (SHA256).
From the root directory, you can run the program with the following command:
cargo run -- [command] [file_path]
The [command] should be either "encrypt" or "decrypt", and [file_path] should be the path to the file you want to encrypt or decrypt.
The file_encrypt_decrypt_aes workspace is a Rust project that provides functionality for file encryption and
decryption using AES (Advanced Encryption Standard) with a 256-bit key. It contains two main files: main.rs
and lib.rs located in the src directory.
The main.rs file contains the main function that drives the program. It reads command-line arguments to determine
whether to encrypt or decrypt a file. If the command is "encrypt", it reads the file, generates a hash of the file
content, asks the user for a password, and then encrypts the file content using the password. The encrypted data, along
with the hash, salt, and initialization vector (IV), are then saved to a new file in base64 format. If the command is "
decrypt", it asks the user for a password, reads the encrypted file, and then decrypts the file content using the
password. It also verifies the hash of the decrypted content against the hash stored in the encrypted file to ensure the
integrity of the data.
The lib.rs file contains the definition of the Config struct and the FileEncryptDecrypt struct. The Config
struct is used to parse and store the command-line arguments. It also provides methods for reading a file, reading a
base64 encoded file, saving data to a file in base64 format, and saving a string to a file. The FileEncryptDecrypt
struct provides methods for hashing file content, verifying a hash, encrypting file content, and decrypting file
content.
The Cargo.toml file in the root directory of the workspace specifies the dependencies of the project, which include
the ring crate for cryptographic operations, the hex crate for encoding and decoding hexadecimal strings,
the base64 crate for encoding and decoding base64 strings, and the rpassword crate for securely reading passwords
from the standard input.
