CWE: CWE-331 \u2014 Insufficient Entropy
The product uses an algorithm or scheme that produces insufficient entropy, leaving patterns or clusters of values that are more likely to occur than others.

Code:
        this.encrypt = function (data, key) {
            if (typeof key === 'undefined' && modules.cryptoModule) {
                var encrypted = modules.cryptoModule.encrypt(data);
                return typeof encrypted === 'string' ? encrypted : (0, base64_codec_1.encode)(encrypted);
            }
            else {
                return crypto.encrypt(data, key);
            }
        };
