Adventure Capitalist Decoding

adcap-decode.js

var lzf = require('lzf');
var crypto = require('crypto');

function DecodeSaveData(data) {
    // Format is: .<Base64 encoded LZF compressed data>|<MD5 hash of data>
    if (data.indexOf('.') !== 0) {
        throw Error('Invalid save data');
    }

    var splitStr = data.substr(1).split('|');
    if (splitStr.length != 2) {
        throw Error('Invalid save data');
    }

    var b64Data = splitStr[0];
    var refHash = splitStr[1];

    var compressedData = new Buffer(b64Data, 'base64');
    var decompressedData = lzf.decompress(compressedData).toString('utf8');

    var computedHash = crypto
        .createHash('md5')
        .update(decompressedData + 'makeripples')
        .digest('hex');

    if (computedHash != refHash) {
        throw Error('Invalid hash');
    }
    
    return JSON.parse(decompressedData);
}

makeripples seems to be the wrong salt for the current adcap version (1.1.1.1202-45e2c59 on Steam).
Any idea where to find a working one?
