我一直有这个问题。
The specified cryptographic algorithm is not supported on this platform.
Exception Details: System.PlatformNotSupportedException: The specified cryptographic algorithm is not supported on this platform.
下面是代码。此代码在安装了 3.5 框架的 Windows XP Pro SP3 和 Windows 2003 Server 上失败。

最佳答案
MSDN表示该类在以下操作系统上受支持:
- Windows 7
- Windows Vista SP1 或更高版本
- Windows XP SP3
- window 服务器 2008 (不支持服务器核心角色)
- Windows Server 2008 R2(服务器核心 不支持角色)
关于c# - 此平台不支持 Diffie-Hellman 加密算法，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/3198954/
