请问各位大师兄，QT如何解密C#用AES(RijndaelManaged )加密的算法？

[lingshan_yandun]

请问，C#中的加密函数（如下），怎么在QT中解密出来？
/// 加密文件函数
/// </summary>
/// <param name="myInFileName">需要加密的文件地址</param>
/// <param name="myOutFileName">加密后的文件地址与名称</param>
/// <param name="myKeyString">密钥：手动输入8~16位</param>

算法应该是抽象的，与具体实现语言应该没有关系吧！你去看下aes的解密实现下应该可以把！

[lingshan_yandun]

嗯 谢谢~~ 我对AES加解密不了解，所以~~~

[wuyueme]

这样生成的密钥可以加密？
