问题 I want to initiate an SSL connection with a remote server using SSLv2. I am using Java. I tried to get the supported protocols in my socket using: String[] suppProtocols=socket.getSupportedProtocols(); System.out.println("The protocols supported for this socket are: "+Arrays.toString(suppProtocols)); and I got this in the output: [SSLv2Hello, SSLv3, TLSv1, TLSv1.1, TLSv1.2] Now, I read that Java does not support SSLv2 and SSLv2Hello only sends hello message using SSLv2. I can't grasp what

问题 I'm writing a client in Java (needs to work both on the desktop JRE and on Android) for a proprietary protocol (specific to my company) carried over TLS. I'm trying to figure out the best way to write a TLS client in Java, and in particular, make sure that it does hostname validation properly. ( Edit: By which, I mean checking that the hostname matches the X.509 certificate, to avoid man-in-the-middle attacks.) JSSE is the obvious API for writing a TLS client, but I noticed from the "Most

问题 I want to create an app use SSLSocket : client send a String to server and server will uppercase that String and send back to client for display. SSLServer public class SSLServer { public static void main(String args[]) throws Exception { try{ //Creaet a SSLServersocket SSLServerSocketFactory factory=(SSLServerSocketFactory) SSLServerSocketFactory.getDefault(); SSLServerSocket sslserversocket=(SSLServerSocket) factory.createServerSocket(1234); //Tạo 1 đối tượng Socket từ serversocket để lắng

问题 The SSLSocket.getEnabledProtocols() method returns the following: [SSLv2Hello, SSLv3, TLSv1] . And indeed, when I call connect() and I have SSL debugging turned on, I see that a v2 client hello is used: main, WRITE: TLSv1 Handshake, length = 81 main, WRITE: SSLv2 client hello message, length = 110 But I have found two (admittedly old) references that say JSSE does not support SSL version 2: From Fundamental Networking in Java: 'SSLv2Hello' is a pseudo-protocol which allows Java to initiate

问题 Has anyone encountered this error before? I'm new to SSL, is there anything obviously wrong with my ClientHello that I'm missing? That exception is thrown with no ServerHello response. Any advice is appreciated. *** ClientHello, TLSv1 RandomCookie: GMT: 1351745496 bytes = { 154, 151, 225, 128, 127, 137, 198, 245, 160, 35, 124, 13, 135, 120, 33, 240, 82, 223, 56, 25, 207, 231, 231, 124, 103, 205, 66, 218 } Session ID: {} Cipher Suites: [SSL_RSA_WITH_RC4_128_MD5, SSL_RSA_WITH_RC4_128_SHA, TLS

问题 I am using Java 6 and am trying to create an HttpsURLConnection against a remote server, using a client certificate. The server is using an selfsigned root certificate, and requires that a password-protected client certificate is presented. I've added the server root certificate and the client certificate to a default java keystore which I found in /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/lib/security/cacerts (OSX 10.5). The name of the keystore file seems to suggest

问题 I am trying to create an SSL connection programmatically using a CUSTOM outbound ssl configuration configured in WAS 8.0.0.13 (IBM Websphere application server that uses java 1.6.0): (Security->SSL certificate and key managemement->Related Items:SSL configurations). The secure connection has been created successfully:a servlet that resides on the WAS server has connected to a server-side Socket listening on 127.0.0.1:1234. The problem is that my preferred cipher suites defined in 'Quality of

问题 I want to a program to verify to create a SSL Sockets using Oracle's SSLSocket class. In my program I want the client to pass its certificate (created using Keytool ). The Server should verify the certificate and then proceed with communication. I want the server to check the certificate of each client that connects to it. Suppose that all the key's (server's and client's) are stored in the Keystore . How do I implement this? Edit: Forgive me if I am not able to convey my question correctly.

问题 I'm building two java applications which have to communicate using SSL two way authentication, I used instructions from here to create client and server certificates. then I built a webService in the server application like this: @RequestMapping(value="/testssl", method = RequestMethod.POST, produces="application/json", consumes="application/json") @ResponseBody public String testSSl(@RequestBody String name) { return = successfully tested; } and I edited tomcat server.xml file to enable SSL
