handshake

Try get webpage: tr := &http.Transport{ TLSHandshakeTimeout: 30 * time.Second, DisableKeepAlives: true, } client := &http.Client{Transport: tr} req, err := http.NewRequest("GET", "https://www.fl.ru/", nil) if err != nil { log.Fatalf("%s\n", err); } resp, err := client.Do(req); if err != nil { log.Fatalf("%s\n", err); } defer resp.Body.Close() Get https://www.fl.ru/ : remote error: handshake failure. If I try to get another HTTPS page - all is OK. That server only supports a few, weak ciphers: TLS_DHE_RSA_WITH_AES_256_CBC_SHA (0x39) DH 1024 bits (p: 128, g: 1, Ys: 128) FS WEAK TLS_DHE_RSA_WITH

I want to have a javascript client process get the HTTP status code that a server is returning when the client makes a websocket upgrade request and that request is unsuccessful. I have my server returning HTTP 400 to indicate that a websocket upgrade is unsuccessful. I am using Google Chrome and when i open the developer console I can see the following message: WebSocket connection to 'wss://' failed: Error during WebSocket handshake: Unexpected response code: 400 However, the onerror handler does not contain this message, it receives a 1006 error but does not indicate that the closure

I am using netty-3.6.6 SSL in my Android app. The handshake() is actually done(Android app is able to send/receive data to/from SSL server) but operationComplete never gets called. I need it getting called to perform some tasks. Anything I missed or did wrong? Thank you. Follows are the settings and the code piece. @Override public ChannelPipeline getPipeline() throws Exception { ChannelPipeline pip = Channels.pipeline(); SSLEngine engine = SslContextFactory.getClientContext().createSSLEngine(); engine.setUseClientMode(true); SslHandler sslHandler = new SslHandler(engine); sslHandler

I am trying to connect an embedded device to smtp.gmail.com:465 using tls1.2 with WolfSSL. The library creates and sends the following clientHello message and receives a handshake failure. 16 03 03 00 4f 01 00 00 4b 03 03 2e 2a ec 85 7f 15 dd 09 5f 22 d1 53 82 60 d7 80 67 28 aa 67 48 ce f0 71 ab 63 d0 b2 3e 55 3a 05 00 00 14 c0 27 c0 23 c0 0a c0 09 c0 07 c0 08 c0 14 c0 13 c0 11 c0 12 01 00 00 0e 00 0d 00 0a 00 08 04 03 02 03 04 01 02 01 Here is the received message; 15 03 03 00 02 02 28 As can be seen in the wireshark screenshot , the following cipher suites are supported by the client; TLS

I've coded websocket server/client with PHP and it worked for me during 2 years. Now it is not working, saying: Error during WebSocket handshake: Incorrect 'Sec-WebSocket-Accept' header value My clientside code is essentially this: socket = new WebSocket("ws://<?= EVENT_SERVER_ADDR ?>:"+EVENT_SERVER_PORT+"<?= EVENT_SERVER_WWW_PATH ?>"); PHP serverside code is this: list ($resource, $host, $connection, $version, $origin, $key, $protocol, $upgrade) = $this->getheaders ($buffer); $this->log ("Handshaking..."); $reply = "HTTP/1.1 101 Switching Protocols\r\n" . "Upgrade: {$upgrade}\r\n" .

(I've already asked the similar question and it turns out that my client key wasn't getting loaded, but I only got one exception further so I'm posting another question.) I'm connecting to a web service which was used before successfully, however now they've changed hostname and sent me two .pem files; one is CA, and other is my new client certificate. (I'm using Java 1.5, Spring + Spring Web Services with Apache httpclient, but I suspect my problem is with certificates, keys and SSL itself.) I've imported both .pem files, as well as host's .crt which I exported from Firefox into my cacerts.
