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 : encode$1(encrypted);
                }
                else {
                    return crypto.encrypt(data, key);
                }
            };
