node-pogo-signature

signature (aka "unknown6") protobuf builder + encryption for node

currently implemented + working in:

https://github.com/cyraxx/pogobuf ( ✨ npm install pogobuf )
https://github.com/Armax/Pokemon-GO-node-api ( npm install pokemon-go-node-api )

0.51 (current)

As of 0.51 native hashing is currently not supported. This library allows both 0.45 and 0.51.

Upgrading to 0.51

If you already have a working 0.45 implementation, the only changes that you need to make are the below

builder.version = "0.51";
builder.useHashingServer("hashing.pogodev.io", 80, "YOUR_KEY", "122");

Full working example

This example uses hardcoded buffers. In a real scenario, you would pass your AuthToken and a list of requests. These can be passed in as encoded protocol's or in their unencoded format.

/// ==============================
/// 0.51 API
/// ==============================
 
/// Your auth ticket
const test = new Buffer(24);
for(let i = 0; i < 24; i++) {
    test[i] = 0;
};
 
/// Fake request
const test2 = new Buffer(24);
for(let i = 0; i < 24; i++) {
    test2[i] = 1;
};
 
/// Fake request #2
const test3 = new Buffer(24);
for(let i = 0; i < 24; i++) {
    test3[i] = 2;
};
 
/// "Unknown22"
const bytes = new Buffer(32);
for(let i = 0; i < bytes.length; i++) {
    bytes[i] = i;
};
 
const builder = new index.Builder({unk22: bytes, time_since_start: 500, time: 1478434897578 });
builder.version = "0.51";
builder.useHashingServer("hashing.pogodev.io", 80, "YOUR_KEY", "122");
builder.setAuthTicket(test, true);
builder.setLocation(0,0,0);
builder.encrypt([test, test2, test3], (err, encryptedSig) => {
    console.log("Builder response " + encryptedSig.toString("hex"));
    assert(encryptedSig.toString("hex") === "000001f4383d7db58229f72dc0c942eddb3c1cad4c80ef4c1c069bb0154d4f16726c5bb11d3587911fab3ce02aa431e4c3a808751503549b80d6e7e51dc17a7ae71e14f7e0a3af491b200dd94e2f777ce009809aeaa0c25c0e0a761768b2d8a0ab38ac7ec725a095b3bf9ff664251c590d62e457683019fbd975482e55cfe02a99a52bd4a8dabd861d6398b3567e1557663d2f74e85fc61f1b29e33bf98174e24b03f18a76c6e01b4e2b39234c8d151dde8900b144fe557d45fb8b9b5d6126a1150a0eee2e6951faf8f349787ed50121becd65c7cbc7ad85fd0191e25241892e2337631f314c691c37d3661b95f49cc8501b3f766bd480aea58a499c3e9cd109c5aae2569a");
});

0.45 (old, unsafe)

The below is for 0.45, which is native (or hash server) hashing. It is no longer considered safe.

use either a hashing server, or native

/// Use hashing
utils.useHashingServer("your ip", 1500);
builder.useHashingServer("your ip", 1500);
/// Do not call this to use native

encrypt usage

module.encrypt(<Buffer> input, <Number> timestamp_since_start, <function> callback)
// or
module.encryptSync(<Buffer> input, <Number> timestamp_since_start)

one-step encrypt usage

If you just want to get stuck in and not worry about setting up your signature, you can use the builder to create everything for you

const builder = new Builder();
builder.setAuthTicket(/* YOUR AUTH TICKET */, true /* true if you've already done encoding */);
builder.setLocation(0,0,0); /* Your location */
builder.encrypt([/* Array of requests */], (err, encryptedSig) => {
    console.log("Builder response " + encryptedSig.toString("hex"));
    /// You can now create the final part of your protobuf
    f_req.unknown6 = new RequestEnvelop.Unknown6({
        unknown1: 6,
        unknown2: new RequestEnvelop.Unknown6.Unknown2({
            unknown1: encryptedSig
        })
    });
});
 
/* Working example with assertion */
const test = new Buffer(24);
for(let i = 0; i < 24; i++) {
    test[i] = 0;
};
 
const bytes = new Buffer(32);
for(let i = 0; i < bytes.length; i++) {
    bytes[i] = i;
};
 
const builder = new index.Builder({unk22: bytes, time_since_start: 500, time: 1478434897578 });
builder.setAuthTicket(test, true);
builder.setLocation(0,0,0);
builder.encrypt([test], (err, encryptedSig) => {
    console.log("Builder response " + encryptedSig.toString("hex"));
    assert(encryptedSig.toString("hex") === "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");
});

Info:

simply passes input and timestamp_since_start through the encrypt method found in the native module. returns (or via callback for async method) the raw encrypted bytes.

Arguments:

input (Buffer): a protobuf-encoded signature message to encrypt
timestamp_since_start (Number): The timestamp since your first request
cb(err, encryptedSignature) (Func): a callback function to execute when encryption by the module has been completed. success when err is null. encryptedSignature is a buffer containing the encrypted information.

basic example

the following will read an input buffer read directly from a file, in the real world this will most likely come from an encoded protobuf structure you generated with your api requests.

var crypto = require('crypto');
var pogoSignature = require('node-pogo-signature');
 
var dump = fs.readFileSync('./signatureBinary.bin');
var time_since = 500;
 
var encryptedSignature = pogoSignature.encryptSync(dump, time_since);
console.log('sync output length: ', encryptedsignature.length);
 
// or, async w/ a callback
 
pogoSignature.encrypt(dump, time_since, function(err, result) {
    if (err) return console.error(err);
 
    console.log('output length: ', result.length)
});
