我一直在使用 bouncy castle 生成自签名证书，并且在更新计算机 A 上运行的 win7 操作系统之前一切顺利。更新后，使用 CERTMGR 查看证书时出现以下错误：此证书的数字无效签名。
同一证书不会在未收到 Microsoft 安全更新的另一台计算机 (B) 上出现错误。然后我在 B 上生成了一个没有错误的新证书，然后将其安装在 A 上，并且发生了同样的错误。（此证书的数字签名无效。）
我回到充气城堡并运行 Org.BouncyCastle.Pkcs.Examples Pkcs12Example 中提供的示例中的代码，我得到不同的相同结果，具体取决于 A 上的计算机，它在 B 上失败，没关系。
有没有人遇到过同样的问题，可以做些什么来解决这个错误？我不想回滚计算机 A 以删除引入此错误的 Microsoft 更新。如果可能的话，我正在寻找一个永久性的修复方法
