一.使用环境

应该是通用的，此测试版本为如图

二.使用代码

1. 运行代码

    QString data  = "123abcAbc.-+";
    qDebug() << "加密：" << QAESEncryption::encodedText(data, "填入自己秘钥");
    qDebug() << "解密：" << QAESEncryption::decodedText(QAESEncryption::encodedText(data, "填入自己秘钥"), "填入自己秘钥");

2. 执行结果

加密： "o933CRxEWGjfio2U0ytHNw=="
解密： "123abcAbc.-+"

三.源代码

1. H文件
