Struct Decrypter

pub struct Decrypter<'a> { /* private fields */ }

A struct responsible for decrypting and extracting files from encrypted game archives.

Implementations

impl<'a> Decrypter<'a>

pub fn new() -> Self

Creates a new Decrypter with empty buffer.

pub fn decrypt( &mut self, data: &'a [u8], ) -> Result<Vec<DecryptedFile>, ExtractError>

Returns Vec of decrypted files.

Parameters

• data: The content of the archive file.

Returns

• Ok(Vec<DecryptedFile>) if files were successfully decrypted.
• Err(ExtractError::InvalidHeader) for invalid header.
• Err(ExtractError::InvalidEngine) for invalid header engine type byte.

Example

use rpgmad_lib::Decrypter;
use std::path::PathBuf;

let data: Vec<u8> = std::fs::read("C:/Game/Game.rgss3a").unwrap();
let decrypted_files = Decrypter::new().decrypt(&data).unwrap();

for file in decrypted_files {
    let path = String::from_utf8_lossy(&file.path);
    let output_path = PathBuf::from("C:/Game").join(path.as_ref());

    if let Some(parent) = output_path.parent() {
        std::fs::create_dir_all(parent).unwrap();
    }

    std::fs::write(output_path, file.content).unwrap();
}

Trait Implementations

impl<'a> Default for Decrypter<'a>

fn default() -> Self

Returns a new Decrypter with default parameters.

Equivalent to calling Decrypter::new().
