我试图对此链接发表评论https://stackoverflow.com/a/39798597/448266，但由于声誉#而无法评论。
我已经尝试了示例并且运行良好，但是当我更改为任意值时，它返回异常消息：Net.Pkcs11Interop.Common.Pkcs11Exception：方法 C_CreateObject 返回 2147483968
我正在使用安全网 HSM SW。
plainKeyValue = Common.HelperFunctions.StringToByteArray("112233445566778899001122334455665566998844335511");
下面是代码快照，我对键值稍作改动（如上）。
