使用jdk中提供的keytool生成SSL证书

Question

我在Web应用程序中使用的密钥库文件已于上周过期.我很久以前就生成了它.所以我开始使用keytool生成新证书.我使用此证书连接事务服务器和Web服务器.我想为此应用程序使用自签名证书.我使用以下命令生成它以生成事务服务器的自签名密钥.

keytool -genkey -keystore keys/SvrKeyStore -keyalg rsa -validity 365 -alias Svr -storepass 123456 -keypass abcdefg -dname "CN=One1, OU=Development1, O=One, L=Bamba, S=Western Prov1, C=S1"

以下commnad为Web应用程序生成密钥库

keytool -genkey -keystore keys/ClientKeyStore -keyalg rsa -validity 365 -alias Web -storepass 123456 -keypass abcdefg -dname "CN=One, OU=Development, O=One, L=Bamba, S=Western Prov, C=SL"

我在事务服务器中使用以下代码来创建套接字连接

          String KEYSTORE = Config.KEYSTORE_FILE;//SvrKeyStore  keystore file
          char[] KEYSTOREPW = "123456".toCharArray();
          char[] KEYPW = "abcdefg".toCharArray();
          com.sun.net.ssl.TrustManagerFactory tmf;

          boolean requireClientAuthentication;

          java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.
                                             Provider());
          java.security.KeyStore keystore = java.security.KeyStore.getInstance(
              "JKS");
          keystore.load(new FileInputStream(KEYSTORE), KEYSTOREPW);

          com.sun.net.ssl.KeyManagerFactory kmf = com.sun.net.ssl.
              KeyManagerFactory.getInstance("SunX509");
          kmf.init(keystore, KEYPW);

          com.sun.net.ssl.SSLContext sslc = com.sun.net.ssl.SSLContext.
              getInstance("SSLv3");
          tmf = com.sun.net.ssl.TrustManagerFactory.getInstance("sunx509");
          tmf.init(keystore);

          sslc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
          SSLServerSocketFactory ssf = sslc.getServerSocketFactory();
          SSLServerSocket ssocket = (SSLServerSocket) ssf.createServerSocket(port);
          ssocket.setNeedClientAuth(true);

但是当我在我的应用程序中使用它并尝试通过Web服务器连接到事务服务器时,它会给出以下异常

任何人都可以告诉我问题出在哪里

Answer 1

首先,避免com.sun.net.ssl直接使用包和类.构建JSSE的体系结构,以便您可以使用工厂并在以后指定提供程序.使用javax.net.ssl.TrustManagerFactory(相同KeyManagerFactory和SSLContext)相反.(我建议使用"PKIX"而不是"SunX509"信任管理器算法,因为它通常是Sun提供商的默认设置,或者更好,使用TrustManagerFactory.getDefaultAlgorithm()).

其次,除非您使用客户端证书身份验证,否则无需在客户端设置密钥管理器.

最后(也许是最重要的),您需要导出您在服务器端生成的自签名证书(仅限证书,而不是私钥),并将其导入您用作信任存储的密钥库中.客户端.

生成证书时,应确保使用CN=the.server.host.name.

keytool -genkey -keystore server-keystore.jks -alias server_alias \
        -dname "CN=the.server.host.name,OU=whateveryoulike" \
        -keyalg "RSA" -sigalg "SHA1withRSA" -keysize 2048 -validity 365

keytool -export -keystore server-keystore.jks -alias server_alias -file server.crt

keytool -import -keystore client-truststore.jks -file server.crt

如果要使用客户端证书身份验证,则需要分别使用client-keystore和server-truststore替换server-keystore和client-truststore来重复此操作.

在这种情况下,server-keystore.jks并且server-truststore.jks可以在同一个文件,但你并不需要(相同的客户端).
