js AES(ECB)加密

js中进行AES(ECB)加密，为什么用到AES加密呢，这个是因为分组加密，加密出来的是16的倍数，在RSA解密处理一个问题。不是16的倍数的不能解密。

ECB模式是不用偏移量的，偏移量我也没搞懂是什么意思，所以不用了吧，毕竟这是个麻烦，还需要定义偏移量。

问题：

1. 带偏移量与不带偏移量的js文件好像是不同的。尝试一下，我记得我做的时候是不同的。
2. 加密的方法的调用也是不同的。

这个是aes不需要iv偏移量的文件。

接下来就是调用的问题：

         * @param encryptString 要加密的字符串
         * @returns {string} 加密后的字符串
         */
        aesEncrypt:function (encryptString) {
            var key = CryptoJS.enc.Utf8.parse(aesPrivateKey);
            var srcs = CryptoJS.enc.Utf8.parse(encryptString);
            var encrypted = CryptoJS.AES.encrypt(srcs, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
            return encrypted.toString();
        }
        /**

        aesDecrypt:function (decryptString) {
            var key = CryptoJS.enc.Utf8.parse(aesPrivateKey);
            var decrypt = CryptoJS.AES.decrypt(decryptString, key, {mode:CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});
            return CryptoJS.enc.Utf8.stringify(decrypt).toString();
        }

自己生成一个aes的密钥试试
