Java “什么是”呢；连接到系统的设备不工作“；RSA加密中的错误？

使用RSA并希望在JAVA中使用公钥进行加密，在c#中使用公钥和私钥进行解密

在java中加密工作正常，但在c#中解密有以下错误： “连接到系统的设备不工作”，这是什么意思

你能提供完整的堆栈跟踪吗？您重新创建

PROVIDER\u RSA\u FULL

有点奇怪，因为它已经定义好了，我不得不查找它，结果发现常量的名称相同。我假设没有其他名为“跟踪器”的容器？您是否使用类似智能卡硬件安全模块（HSM）的东西？您的系统在尝试访问HSM时可能会遇到错误。@AxelKemper否我不知道您是否可以提供完整的堆栈跟踪？您重新创建
