re-unplayplay v1.2.8

re-unplayplay

A rewritten version of unplayplay, which is a slightly edited version of pbdecrypt.cc. \ This library is implementing various cryptography algorithms used by the spotify's DRM called playplay, you can refer to votify to see how it should be used.

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()  # returns bytes

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

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

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

TypeScript

import { decryptKey, bindKey, decryptAndBindKey, getToken } from 're-unplayplay';

// Get the associated token
getToken(); // returns Buffer

// Decrypt the encrypted key
const decrypted = decryptKey(Buffer.from('01', 'hex')); // returns Buffer

// Bind decrypted key
const bind_result = bindKey(decrypted, '01'); // returns Buffer

// Decrypt and bind in one call
const result = decryptAndBindKey(Buffer.from('01', 'hex'), '01'); // returns Buffer

JavaScript

const re_unplayplay = require('re-unplayplay');

// same as typescript
