我想创建SSL连接。我创建了密钥库。并试图使用x509。
final KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");字符串
但我得到下面的异常控制台运行后。
Java.security. NoSuchromException：X509 KeyManagerFactory not available at sun.security.jca.GetInstance.getInstance（Unknown Source）at javax.net.ssl.KeyManagerFactory.getInstance（Unknown Source）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型

算法提供程序无法识别您使用的参数
X509。正如所描述的getInstance（String算法）的原因是清楚的。
如果没有Provider支持指定算法的KeyManagerFactorySpi实现，则抛出NoSuchalummException。
标准算法描述为here
我猜他们在
KeyManagerFactory中支持PKIX, SunX509这两个算法所以你必须使用
SunX509而不是X509。看这里的表格

阅读堆栈跟踪告诉你的内容：
java.security. NoSuchromException：找不到X509 KeyManagerFactory
X509算法在您使用的安全提供程序中不可用。但是，下面的代码应该可以为您工作：字符串
请看一下这个Code Ranch article，它讨论了你的问题，还展示了如何从你的提供商那里找到可用的安全算法。

使用“SunX509”的问题在于它是特定于Oracle JRE的，在IBM JRE中不起作用，IBM JRE的默认值是“IbmX509”。与供应商无关的更好的解决方案是：
字符串
默认算法由
<JRE_HOME>/lib/security/java.security中的安全属性“ssl.keyManagerFactory.algorithm”定义，在Oracle中默认为“SunX509”，在IBM JRE中默认为“IbmX509”（至少对于Java 8是这样）。yvgpqqbh4#
首先检查所需的算法是否在JDK jre的java.security中可用在我的情况下，我只是改变了算法的顺序，并在 Java.security中添加了一个安全提供程序，它工作了。
1.增加的安全性提供：
security.provider.12=sun.x.rsa.SunRsaSign
1.改变算法顺序：
发件人：
ssl.KeyManagerFactory.algorithm=SunX509
ssl.TrustManagerFactory.algorithm=PKIX
到
ssl.TrustManagerFactory.algorithm=PKIX
ssl.KeyManagerFactory.algorithm=SunX509
java.security路径：\jdk1.7.0_25\jre\lib\security\java.security
使用下面的代码检查您的JDK是否支持SunX509算法
