Java SSL SSLHandshakeException 握手失败

4

我正在使用Java 8，并使用SSLSocket请求以下网址：https://www.flixbus.de/sites/default/files/6_jetzt_buchen_button_tiny.png，但总是遇到握手错误。尝试使用socket.setEnabledProtocols()强制使用特定协议也没有帮助。顺便说一下，所有其他Web服务器都能正常工作，因此问题可能与我的代码无关。这个错误即使没有任何SSL/TLS协议限制也会发生。您有什么想法？使用选项“javax.net.debug = all”的输出如下：

DEBG getSecureScocket: Supported protocols:
- SSLv2Hello
- SSLv3
- TLSv1
- TLSv1.1

你尝试过启用所有支持的协议而不仅仅是TLSv1.2吗？只是为了看看是否存在问题（因为正如你可能已经知道的那样，SSLvX不再推荐在生产中使用）。 - morgano

是的。首先我使用了默认设置，启用了所有协议。也不起作用。我在这里找到了解决方案（https://dev59.com/nG445IYBdhLWcg3w0dZD#4686924）。这就是为什么我限制了协议并希望它能有所帮助。 - Enzo Matrix

这个错误可能是因为你使用的Tls1.2服务器不支持

- Pham Thai Thinh

我限制使用TLS1.2，因为服务器响应的是TLS1.2。至少从日志中我理解是这样的。如果我不进行任何协议限制，它也无法工作。 - Enzo Matrix

该网站需要SNI（服务器名称指示），也就是说，如果没有SNI，则握手将失败。所有现代浏览器都支持SNI，但并非所有编程语言中的SSL堆栈都支持SNI或默认使用它。请参见http://www.vimino.com/2014/01/jep-114-tls-sni-extension-sunjsse-behavior-changes/，了解如何在Java 8中使用SNI。

您可以使用openssl s_client检查此类行为：

# without SNI
$ openssl s_client -connect www.flixbus.de:443
CONNECTED(00000003)
140612985652896:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure:s23_clnt.c:770:
....
New, (NONE), Cipher is (NONE)

# with SNI
$ openssl s_client -connect www.flixbus.de:443  -servername 'www.flixbus.de'
CONNECTED(00000003)
...
New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES128-GCM-SHA256

或者您可以使用 analyze.pl：

$ perl analyze-ssl.pl  www.flixbus.de
-- www.flixbus.de port 443
 * maximum SSL version  : TLSv1_2 (SSLv23)
 ...
 * SNI supported        : SSL upgrade fails without SNI
