node-pogo-signature

signature (aka "unknown6") protobuf builder + encryption for node (now in native javascript!)

includes some easy (still undocumented) signature building helper libs - will document soon

currently implemented + working in:

• https://github.com/cyraxx/pogobuf ( ✨ npm install pogobuf )
• https://github.com/Armax/Pokemon-GO-node-api (not available via npm yet )

encrypt usage

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

Info:

simply passes input and iv 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
• initVector (Buffer): a 32-byte random initialization vector to encrypt the data against
• cb(err, encryptedSignature) (Func): a callback function to execute when encryption by the moldue 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 iv = crypto.randomBytes(32);

var encryptedSignature = pogoSignature.encryptSync(dump, iv);
console.log('sync output length: ', encryptedsignature.length);
console.log('sync output iv: ', encryptedsignature.slice(0, 32).toString('hex'));

// or, async w/ a callback

pogoSignature.encrypt(dump, iv, function(err, result) {
	if (err) return console.error(err);

	console.log('output length: ', result.length)
    console.log('output iv: ', result.slice(0, 32).toString('hex'));
});
