推荐答案

我的建议是，您必须在.lic中使用哈希数据.因为如果您可以解密加密的数据，那么任何人都可以解密它.因此，您在那里遇到了安全问题.

请记住，不建议在Silverlight中从客户端PC读取文件.可能是该课程可以帮助您在服务器和服务器上Silverlight的客户场景: AesManaged

希望它能以任何方式提供帮助.

My advice is that you must use hashed data in your .lic. Because if you can decrypt the encrypted data anyone can decrypt it. So, you have a security issue there.

Remember that in silverlight isn''t recommendable to read file from client PC. May be this class help you in server & client scenario for Silverlight: AesManaged

Hope it helps in any way.
