Function hexcrypt::encrypt::encrypt

pub fn encrypt(
    path: impl AsRef<Path> + Clone,
    size: Option<String>,
    out_path: Option<PathBuf>
) -> Result<(), HexCryptError>

Encrypts the UTF-8 encoded text from the specified file and converts it into an RGB image.

Arguments

• path - A reference to a path that points to the file containing the text to be encrypted.
• size - An optional String representing the custom size of the image (e.g., “16x32”).
• out_path - An optional PathBuf representing the output path for the generated image. If None, path is used insted (with .png extension)

Errors

This function can return a HexCryptError enum that represents different error cases, including I/O errors, invalid image sizes, and issues related to image creation and processing.

Examples

use std::path::PathBuf;
use hexcrypt::encrypt;

let input_path = PathBuf::from("input.txt");
let output_path = PathBuf::from("output.png");
let size = Some("16x32".to_string());

match encrypt(input_path, size, Some(output_path)) {
    Ok(_) => println!("Encryption successful!"),
    Err(e) => eprintln!("Error: {:?}", e),
}
