Tomcat是否支持TLS v1.2？

我想知道Apache Tomcat是否支持TLS v1.2协议.我没有找到任何关于此的文档!谢谢!

我有一个类似用途的情况下,这是为了让Tomcat的7,严格只使用TLSv1.2工作,而不是退回到较早的SSL协议,如TLSv1.1或SSLv3的.以下步骤将回答如何启用Tomcat以支持TLSv1.2.

我使用的:C:\ Apache的Tomcat的7.0.64-64bit和C:\ Java64\jdk1.8.0_60.

遵循以下指示:https://tomcat.apache.org/tomcat-7.0-doc/security-howto.html.Tomcat设置SSL支持相对简单.

从许多参考文献中我测试了很多组合,最后我发现1将强制Tomcat 7仅接受TLSv1.2.触摸需要2个地方:

1)在C:\ apache-tomcat-7.0.64-64bit\conf\server.xml中

<Connector port="8443" 
 protocol="org.apache.coyote.http11.Http11Protocol"
 maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
 keystoreFile="ssl/.keystore" keystorePass="changeit"
 clientAuth="false" sslProtocol="SSL" sslEnabledProtocols="TLSv1.2" />

哪里

keystoreFile =本地自签名信任库

org.apache.coyote.http11.Http11Protocol = JSSE BIO实现.

我们不使用org.apache.coyote.http11.Http11AprProtocol,因为它是由OpenSSL的供电.底层的openssl将回退以支持早期的SSL协议.

2)启动Tomcat时,启用以下环境参数.

set JAVA_HOME=C:\Java64\jdk1.8.0_60
set PATH=%PATH%;C:\Java64\jdk1.8.0_60\bin
set CATALINA_HOME=C:\apache-tomcat-7.0.64-64bit
set JAVA_OPTS=-Djdk.tls.client.protocols="TLSv1.2" -Dsun.security.ssl.allowUnsafeRenegotiation=false -Dhttps.protocols="TLSv1.2"

需要JAVA_OPTS限制,否则Tomcat(由Java8提供支持)将回退以支持早期的SSL协议.

启动Tomcat C:\ apache-tomcat-7.0.64-64bit\bin\startup.bat

我们可以看到JAVA_OPTS出现在Tomcat启动日志中.

然后,我们可以使用openssl命令来验证我们的设置.首先使用TLSv1.1协议连接localhost:8443.Tomcat拒绝回复服务器证书.

C:\OpenSSL-Win32\bin>openssl s_client -connect localhost:8443 -tls1_1

CONNECTED(000001C0)

使用TLSv1.2协议连接localhost:8443,Tomcat使用证书回复ServerHello:

C:\OpenSSL-Win32\bin>openssl s_client -connect localhost:8443 -tls1_2

这证明Tomcat现在严格响应TLSv1.2请求.
