Usage

C++

#include <unplayplay.hpp>

int main(const int argc, const char* argv[]) {
    if (argc < 2) {
        std::cerr << "usage: " 
                  << argv[0] 
                  << " {file_id} {obfuscated_key}" 
                  << std::endl;
        return 1;
    }

    const auto file_id = unplayplay::util::FileId(
        argv[1]
    );
    const auto obfuscated_key = unplayplay::util::Key(
        argv[2]
    );
    
    const auto decrypted_key = unplayplay::decrypt_key(
        obfuscated_key
    );
    const auto result = unplayplay::bind_key(
        decrypted_key, file_id
    );

    for (std::size_t i = 0; i < result.size(); ++i) {
        std::cout << std::setw(2) 
                  << std::setfill('0') 
                  << std::hex 
                  << static_cast<int>(result[i]);
    }
    std::cout << std::endl;

    return 0;
}

Python

from re_unplayplay import decrypt_key, bind_key, decrypt_and_bind_key, get_token

# Get the associated token
get_token().hex()

# Decrypt the encrypted key
decrypted = decrypt_key(bytes.fromhex('01'))

# Bind decrypted key
bind_result = bind_key(decrypted, '01')

# Decrypt and bind in one call
result = decrypt_and_bind_key(bytes.fromhex('01'), '01')
