SSLHandshakeException:收到致命警报:在tomcat 7服务器上设置密码时的handshake_failure

Question

我有一个Tomcat7 Web服务器,我尝试通过将此连接器添加到server.xml文件来配置为接受安全连接:

<Connector SSLEnabled="true"
           acceptCount="100"
           connectionTimeout="20000"
           executor="tomcatThreadPool"
           keyAlias="server"
           keystoreFile="c:\opt\engine\conf\tc.keystore"
           keystorePass="o39UI12z"
           maxKeepAliveRequests="15"
           port="8443"
           protocol="HTTP/1.1"
           redirectPort="8443"
           scheme="https"
           secure="true"
           sslProtocol="TLS"/>

我正在使用使用此命令生成的自签名证书:

%JAVA_HOME%/bin/keytool -genkeypair -keystore c:\opt\engine\conf\tc.keystore -storepass o39UI12z-keypass o39UI12z-dname "cn=Company, ou=Company, o=Com, c=US" -alias server -validity 36500

在客户端,我有一个使用连接服务器的spring应用程序RestTemplate.在应用程序上下文启动时,我以restTemplate这种方式初始化实例:

final ClientHttpRequestFactory clientHttpRequestFactory =
        new MyCustomClientHttpRequestFactory(new NullHostNameVerifier(), serverInfo);
    restTemplate.setRequestFactory(clientHttpRequestFactory);

MyCustomClientHttpRequestFactory类如下所示:

public class MyCustomClientHttpRequestFactory  extends SimpleClientHttpRequestFactory {

private static final Logger LOGGER = LoggerFactory
    .getLogger(MyCustomClientHttpRequestFactory.class);

private final HostnameVerifier hostNameVerifier;
private final ServerInfo serverInfo;

public MyCustomClientHttpRequestFactory (final HostnameVerifier hostNameVerifier,
    final ServerInfo serverInfo) {
    this.hostNameVerifier = hostNameVerifier;
    this.serverInfo = serverInfo;
}

@Override
protected void prepareConnection(final HttpURLConnection connection, final String httpMethod)
    throws IOException {
    if (connection instanceof HttpsURLConnection) {
        ((HttpsURLConnection) connection).setHostnameVerifier(hostNameVerifier);
        ((HttpsURLConnection) connection).setSSLSocketFactory(initSSLContext()
            .getSocketFactory());
    }
    super.prepareConnection(connection, httpMethod);
}

private SSLContext initSSLContext() {
    try {
        System.setProperty("https.protocols", "TLSv1");

        // Set ssl trust manager. Verify against our server thumbprint
        final SSLContext ctx = SSLContext.getInstance("TLSv1");
        final SslThumbprintVerifier verifier = new SslThumbprintVerifier(serverInfo);
        final ThumbprintTrustManager thumbPrintTrustManager =
            new ThumbprintTrustManager(null, verifier);
        ctx.init(null, new TrustManager[] { thumbPrintTrustManager }, null);
        return ctx;
    } catch (final Exception ex) {
        LOGGER.error(
            "An exception was thrown while trying to initialize HTTP security manager.", ex);
        return null;
    }
}

直到这里一切正常.当我在SslThumbprintVerifier类中放置一个断点时,代码到达了这一点,也达到了NullHostNameVerifier类.这在生产中经过测试并且运行良好.

现在我想通过限制密码套件来扩展安全性,并将此属性添加到我在开头提供的Connector:

ciphers="TLS_KRB5_WITH_RC4_128_SHA,SSL_RSA_WITH_RC4_128_SHA,SSL_DHE_RSA_WITH_AES_256_CBC_SHA,SSL_RSA_WITH_AES_256_CBC_SHA,SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA,SSL_RSA_WITH_3DES_EDE_CBC_SHA,SSL_DHE_RSA_WITH_AES_128_CBC_SHA,SSL_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_RC4_128_SHA,TLS_RSA_WITH_3DES_EDE_CBC_SHA,TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_DHE_RSA_WITH_AES_128_CBC_SHA,TLS_DHE_RSA_WITH_AES_256_CBC_SHA,TLS_KRB5_WITH_3DES_EDE_CBC_SHA"

现在,当我运行客户端代码时,我得到以下异常:

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

这种情况发生在该restTemplate.doExecute()方法中.代码不会像添加密码之前那样到达指纹验证程序类,也不会到达主机名验证程序类.

在调试中我检查了ctx.getSocketFactory().getSupportedCipherSuites()哪个显示:

[SSL_RSA_WITH_RC4_128_MD5, SSL_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_DSS_WITH_AES_128_CBC_SHA, TLS_DHE_DSS_WITH_AES_256_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA, SSL_RSA_WITH_DES_CBC_SHA, SSL_DHE_RSA_WITH_DES_CBC_SHA, SSL_DHE_DSS_WITH_DES_CBC_SHA, SSL_RSA_EXPORT_WITH_RC4_40_MD5, SSL_RSA_EXPORT_WITH_DES40_CBC_SHA, SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA, SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA, TLS_EMPTY_RENEGOTIATION_INFO_SCSV, SSL_RSA_WITH_NULL_MD5, SSL_RSA_WITH_NULL_SHA, SSL_DH_anon_WITH_RC4_128_MD5, TLS_DH_anon_WITH_AES_128_CBC_SHA, TLS_DH_anon_WITH_AES_256_CBC_SHA, SSL_DH_anon_WITH_3DES_EDE_CBC_SHA, SSL_DH_anon_WITH_DES_CBC_SHA, SSL_DH_anon_EXPORT_WITH_RC4_40_MD5, SSL_DH_anon_EXPORT_WITH_DES40_CBC_SHA, TLS_KRB5_WITH_RC4_128_SHA, TLS_KRB5_WITH_RC4_128_MD5, TLS_KRB5_WITH_3DES_EDE_CBC_SHA, TLS_KRB5_WITH_3DES_EDE_CBC_MD5, TLS_KRB5_WITH_DES_CBC_SHA, TLS_KRB5_WITH_DES_CBC_MD5, TLS_KRB5_EXPORT_WITH_RC4_40_SHA, TLS_KRB5_EXPORT_WITH_RC4_40_MD5, TLS_KRB5_EXPORT_WITH_DES_CBC_40_SHA, TLS_KRB5_EXPORT_WITH_DES_CBC_40_MD5]

并检查ctx.getSocketFactory().getDefaultCipherSuites():

[SSL_RSA_WITH_RC4_128_MD5, SSL_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_DSS_WITH_AES_128_CBC_SHA, TLS_DHE_DSS_WITH_AES_256_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA, SSL_RSA_WITH_DES_CBC_SHA, SSL_DHE_RSA_WITH_DES_CBC_SHA, SSL_DHE_DSS_WITH_DES_CBC_SHA, SSL_RSA_EXPORT_WITH_RC4_40_MD5, SSL_RSA_EXPORT_WITH_DES40_CBC_SHA, SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA, SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA, TLS_EMPTY_RENEGOTIATION_INFO_SCSV]

最后ctx.getSupportedSSLParameters().getCipherSuites():

[SSL_RSA_WITH_RC4_128_MD5, SSL_RSA_WITH_RC4_128_SHA, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_DSS_WITH_AES_128_CBC_SHA, TLS_DHE_DSS_WITH_AES_256_CBC_SHA, SSL_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA, SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA, SSL_RSA_WITH_DES_CBC_SHA, SSL_DHE_RSA_WITH_DES_CBC_SHA, SSL_DHE_DSS_WITH_DES_CBC_SHA, SSL_RSA_EXPORT_WITH_RC4_40_MD5, SSL_RSA_EXPORT_WITH_DES40_CBC_SHA, SSL_DHE_RSA_EXPORT_WITH_DES40_CBC_SHA, SSL_DHE_DSS_EXPORT_WITH_DES40_CBC_SHA, TLS_EMPTY_RENEGOTIATION_INFO_SCSV, SSL_RSA_WITH_NULL_MD5, SSL_RSA_WITH_NULL_SHA, SSL_DH_anon_WITH_RC4_128_MD5, TLS_DH_anon_WITH_AES_128_CBC_SHA, TLS_DH_anon_WITH_AES_256_CBC_SHA, SSL_DH_anon_WITH_3DES_EDE_CBC_SHA, SSL_DH_anon_WITH_DES_CBC_SHA, SSL_DH_anon_EXPORT_WITH_RC4_40_MD5, SSL_DH_anon_EXPORT_WITH_DES40_CBC_SHA, TLS_KRB5_WITH_RC4_128_SHA, TLS_KRB5_WITH_RC4_128_MD5, TLS_KRB5_WITH_3DES_EDE_CBC_SHA, TLS_KRB5_WITH_3DES_EDE_CBC_MD5, TLS_KRB5_WITH_DES_CBC_SHA, TLS_KRB5_WITH_DES_CBC_MD5, TLS_KRB5_EXPORT_WITH_RC4_40_SHA, TLS_KRB5_EXPORT_WITH_RC4_40_MD5, TLS_KRB5_EXPORT_WITH_DES_CBC_40_SHA, TLS_KRB5_EXPORT_WITH_DES_CBC_40_MD5]

据我所知,如果客户端支持/启用的密码套件与服务器支持的密码套件之间存在交叉,那么它应该可以工作(例如,我们有这样的交集SSL_RSA_WITH_RC4_128_SHA).然而,我收到了这个错误.

在下一步中,我添加了这个java参数:

-Djavax.net.debug=ssl,handshake,failure

日志只显示了client-hello,没有server-hello响应:

从server.xml中删除密码时,它再次起作用. 另外我会提到我在同一台机器上测试服务器和客户端.我尝试将客户端请求中的服务器ip设置为"localhost"和实际的机器ip,但在两种情况下都不起作用.此外,我让这台服务器在不同的Linux机器上运行(密钥库是在linux机器上生成的,当然还有linux路径)并且仍然 - 它没有密码,并且停止使用密码.

Answer 1

好吧,我解决了这个问题.看来,通过创建自签名证书,使用keytool,而不提供-keyalg参数使得密钥对算法默认为DSA.我的密码套件都没有包含DSA算法.在这种情况下,虽然客户端和服务器在它们的密码套件之间有交集,但它们都不适用于密钥算法.

-keyalg RSA在生成密钥库时添加,解决了问题.
