Crate rexor 

This library provides simple file encryption and decryption using XOR logic. It allows you to encode or decode any file with a defined password, producing .rxor encrypted files.

Example: Encoding a file

use rexor::encode;

fn main() -> std::io::Result<()> {
    let input = "example.txt";
    let password = "password123";

    // Encode the file into "example.txt.rxor"
    let output = encode(input, password, None)?;
    println!("Encoded file saved at: {}", output);

    Ok(())
}

Example: Decoding a file

use rexor::decode;

fn main() -> std::io::Result<()> {
    let input = "example.txt.rxor";
    let password = "password123";

    // Decode the file back to its original form
    let output = decode(input, password, None)?;
    println!("Decoded file saved at: {}", output);

    Ok(())
}

Example: Custom output path

use rexor::{encode, decode};

fn main() -> std::io::Result<()> {
    let input = "example.txt";
    let password = "password123";

    // Encode to a custom location
    let encoded = encode(input, password, Some("encrypted/output.rxor"))?;

    // Decode back into another file
    let decoded = decode(&encoded, password, Some("decrypted/example.txt"))?;

    println!("Encoded: {}", encoded);
    println!("Decoded: {}", decoded);

    Ok(())
}

Errors

The functions return std::io::Result<String>. Typical errors include:

• Invalid input paths or missing files
• Empty password (std::io::ErrorKind::InvalidInput)
• I/O issues while reading or writing files

Functions

decode

Decodes a previously XOR-encoded file using the provided password. Returns the output path of the decoded file.

encode

Encodes a file using XOR with the provided password and input path. Returns the output path of the encoded file.
