java.security.NoSuchAlgorithmException:X509 KeyManagerFactory不可用

Question

我想创建SSL连接.我创建了密钥库.并尝试使用x509.

 final KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");

但是我跑完后在控制台上遇到异常.

java.security.NoSuchAlgorithmException:X509 KeyManagerFactory在javax.net.ssl.KeyManagerFactory.getInstance(未知来源)的sun.security.jca.GetInstance.getInstance(未知来源)中不可用SSLContext sc = SSLContext.getInstance(connectionType); final char [] keyPassPhrase ="changeit".toCharArray(); // String [] array = Security.getProviders(); final KeyStore ks = KeyStore.getInstance("jks");

        ks.load(new FileInputStream("ClientKeyStore"), keyPassPhrase);
        provider();
        final KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509"); // this line is problem

        // SunX509 : supporting only: [TLSv1, TLSv1.1, TLSv1.2]
        kmf.init(ks, keyPassPhrase);

        sc.init(kmf.getKeyManagers(), new TrustManager[] {
                new X509TrustManager(){
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return null;
                    }
                    @Override
                    public void checkClientTrusted(X509Certificate[] arg0, String arg1)
                            throws CertificateException {

                    }
                    public void checkServerTrusted(X509Certificate[] arg0, String arg1)
                            throws CertificateException {
                    }
                }
        },new SecureRandom());
        SSLSocketFactory factory = sc.getSocketFactory();
        SSLSocket socket=null;
        try{
            //socket = (SSLSocket) factory.createSocket("XXXX",xxxx);/
            socket = (SSLSocket) factory.createSocket(ipAddress, Integer.parseInt(ports[portIndex]));

            //convert to array
            String[] cipherSelectedArray;
            if(isSupported == 1 ) {
                cipherSelectedArray = new String[] {msupportedcipherList.get(cipherIndex).trim()};
            }
            else {
                cipherSelectedArray = new String[] {mnotSupportedcipherList.get(cipherIndex).trim()};
            }

            String []mselectedSSLOrTLSVersionArrray = new String[] {mselectedSSLOrTLSVersion};   // if passing these --> getting connection timeout

            socket.setEnabledProtocols(mselectedSSLOrTLSVersionArrray);
            socket.setEnabledCipherSuites(cipherSelectedArray);
            for(int i = 0; i<cipherSelectedArray.length ; i++) {
                //System.out.println("ciphers are :" +  cipherSelectedArray[i]);
            }


            socket.setSoTimeout(15000);

            socket.addHandshakeCompletedListener(new HandshakeCompletedListener() {

                @Override
                public void handshakeCompleted(HandshakeCompletedEvent event) {
                    ////System.out.println("completed");

                }
            });



            socket.startHandshake(); //handshake                                            as "SunX509" does not support SSL. I need to create above one. Can someone help.   And also with "SunX509" i am getting                                              java.lang.IllegalArgumentException: Cannot support TLS_RSA_WITH_AES_256_CBC_SHA with currently installed providers problem with some ciphers. please help

Answer 1

X509算法提供程序无法识别您使用的参数.

如描述getInstance(String算法)的原因很清楚.

NoSuchAlgorithmException - 如果没有Provider支持指定算法的KeyManagerFactorySpi实现.

这里描述了标准算法

我猜他们支持 PKIX, SunX509这两个算法KeyManagerFactory

所以你必须使用SunX509而不是X509.
