尝试使用 SSL 将 Java 客户端应用程序连接到 C++ 服务器时收到错误消息。
Java 客户端应用程序显示的错误消息是：
java.security.NoSuchAlgorithmException：构造实现时出错（算法：默认，提供程序：SunjSSE，类 sun.security.ssl.SSLContextImpl$DefaultSSLContext）。
我使用 openssl 3 创建根证书、服务器证书和客户端证书，并将其复制到下面。根证书是自签名的。这一切都是为了在开发环境中进行测试。客户端证书的签名算法是sha256withRSAEncryption
Java应用程序使用Java OpenJDK 11。操作系统是Red Hat 9.1。
以下是我的 java.security 文件中的提供者列表及其顺序：注意 SunRsaSign 优先于 SunJSSE。
security.provider.1=SUN
security.provider.2=SunRsaSign
security.provider.3=SunEC
security.provider.4=SunJSSE
security.provider.5=SunJCE
security.provider.6=SunJGSS
security.provider.7=SunSASL
security.provider.8=XMLDSig
security.provider.9=SunPCSC
security.provider.10=JdkLDAP
security.provider.11=JdkSASL
security.provider.12=SunPKCS11
#security.provider.1=SunPKCS11 ${java.home}/lib/security/nss.cfg
对可能导致此错误的原因有何想法？
我搜索了 stackoverflow 和其他地方，寻找发生此错误的原因。我看到一些提及 SunjSSE 不支持 sha256withRSAEncryption，但 SunRsaSign 确实支持 sha256withRSAEncryption。我还看到了一些参考资料，指出 java.security 文件中提供程序的顺序很重要。我还注意到错误消息指出提供程序是 SunjSSE，但 java.security 中的提供程序名称是 SunJSSE。不确定提供商名称是否区分大小写？
不确定我可以提供哪些其他信息来帮助解决这个问题？我很乐意发布任何需要的内容。
下面是我用来连接服务器的测试客户端证书：
