我有板岩集成的要求。我有一个用于发布数据的代码，但我希望它能转换成 java。以下是引用代码:
'''string host = @url;
string certName = @"myfile.pfx"; // i am having .pem file
string password = @"password"; // no password
var certificate = new System.Security.Cryptography.X509Certificates.X509Certificate2(certName,
password);
System.Net.ServicePointManager.ServerCertificateValidationCallback = (a, b, c, d) => true;
var req = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(host);
req.PreAuthenticate = true;
req.Credentials = new System.Net.NetworkCredential("username", "");
req.ClientCertificates.Add(certificate);
req.Method = "POST";
req.ContentType = "text/xml";
string postData = "<hello>world</hello>";
byte[] postBytes = System.Text.Encoding.UTF8.GetBytes(postData);
req.ContentLength = postBytes.Length;
req.GetRequestStream().Write(postBytes, 0, postBytes.Length);
req.GetRequestStream().Close();
var resp = req.GetResponse();'''
请帮助将 c 代码转换为 java 代码或从 .pem 文件生成证书。我已经检查了谷歌中的许多链接，但它对我不起作用。从 .pem 文件生成证书时抛出不完整的数据或空数据。
提前致谢
最佳答案
如果您想阅读证书，可以使用下面的 java 代码。
CertificateFactory fact = CertificateFactory.getInstance("X.509");
FileInputStream is = new FileInputStream (pemfilepath);
X509Certificate cer = (X509Certificate) fact.generateCertificate(is);
PublicKey key = cer.getPublicKey();
如果你想要别的东西，请告诉我
