我正在尝试使用 spongycastle 1.51 在 android 上使用 mina sshd 0.12.0。

我已按照可用的说明进行操作，使用注册 Spongycastle

static {
  Security.insertProviderAt( new org.spongycastle.jce.provider.BouncyCastleProvider(), 1);
}

Spongycastle 已被验证为干净地注册并请求算法“EC”：

java.security.KeyPairGenerator.getInstance("EC");

工作正常。

当我最终尝试建立与服务器的 ssh 连接时，它失败并显示以下堆栈跟踪：

我在这里不知所措。插入的提供程序是否以某种方式线程本地？

我很感谢任何提示。
