这是一个基本的安全应用程序，我只想加密和解密一些数据现在我的问题是在文本框中显示网络文本并取回该文本然后将其转换为字节数组并且在解密时我得到了错误

Error: ECB mode cipher length must be a multiple of blocksize 16
    at com.hurlant.crypto.symmetric::ECBMode/decrypt()

在转换为字符串时进行 Aes 加密后，我添加了以下代码，最后一切都正确了......

            aes.encrypt(cleartextBytes);
            trace("after Encription-------------"+cleartextBytes.length+cleartextBytes);
            cleartextBytes.position=0;
            var myEncoder:Base64Encoder = new Base64Encoder();

            myEncoder.encodeBytes(cleartextBytes);

            cyperText.text=myEncoder.toString();

            trace("Encoded string length"+cyperText.text.length);
