这是我第一次从事认证工作，对此我完全陌生。 我在编译过程中出错了，我在互联网上找不到任何关于它的信息，也没有发现相同的错误。自 4 天以来，我一直在努力解决这个问题，我什么也做不了 :( 非常感谢您的帮助。谢谢。
这是我的代码: 主类
package tn.ance.signature;
import java.security.*;
import java.security.cert.X509Certificate;
public class main_project {
public static void main(String[] args) {
chargement_fichier cf = new chargement_fichier();
KeyStore ks = cf.charger_fichier();
char[] password = cf.getPassword();
// RECUPERATION DU COUPLE CLE PRIVEE/PUBLIQUE ET DU CERTIFICAT PUBLIQUE
X509Certificate cert = null;
PrivateKey privatekey = null;
PublicKey publickey = null;
recuperation_cles_cert recup =new recuperation_cles_cert();
privatekey = recup.getPrivatekey();
publickey = recup.getPublickey();
cert = recup.getCert();
System.out.println("Private Key Format:");
System.out.println(privatekey.getFormat());
System.out.println("Private Key Algorithme:");
System.out.println(privatekey.getAlgorithm());
System.out.println("Public Key Format:");
System.out.println(publickey.getFormat());
System.out.println("Public Key Algorithme:");
System.out.println(publickey.getAlgorithm());
System.out.println("Certification:");
System.out.println("SubjectDN:");
System.out.println(cert.getSubjectDN());
System.out.println("Not After:");
System.out.println(cert.getNotAfter());
System.out.println("Not Before:");
System.out.println(cert.getNotBefore());
}

更新 我将 bcprov-jdk16-1.45 添加到文件夹 C:\Program Files\Java\jdk1.7.0_75\lib 并将其添加到项目中的外部 jar 路径，但现在出现此错误

最佳答案
尝试使用 jdk15on-152 - 1.45 版本已停产。名称中带有 jdk15on 的 jar 版本适用于 JDK 1.5 到 JDK 1.8(我们最初尝试使用 jdk15+，但结果 maven 无法处理 +)。
