Conscrypt with jdk8 to enable ALPN for http2

阅读更多关于 Conscrypt with jdk8 to enable ALPN for http2

问题 I have been searching how to implement Conscrypt SSL provider using conscrypt-openjdk-uber-1.4.1.jar for jdk8 to support ALPN for making a http2(using apache httpclient 5) connection to a server as jdk8 does not support ALPN by default or the other solution is to migrate to jdk9(or higher) which is not feasible for now as our product is heavily dependent on jdk8 I have been searching extensively for some docs or examples to implement but I could not find one. I have tried to insert conscrypt

阅读更多关于 Browser won't upgrade to H2 altough “Upgrade” headers are sent

问题 On my webserver I'm trying to get H2 (http2) to work. Installed Apache 2.4.20 via the "ondrej" repository. I tested on a Debian 8 and Ubuntu 14.04 server, but I keep running into the same problems. I have OpenSSL 1.0.2 and SSL vhosts running. The strange thing is that the upgrade headers (Connection: upgrade and Upgrade: h2) are sent. When I do some external server testing I get the responses that h2 is running properly with ALPN support. But the problem is the browsers I tested on (Chrome

TLS ALPN in Python 2.7

阅读更多关于 TLS ALPN in Python 2.7

问题 I'm working on some HTTP/2 client and I want to add SSL support. According to the RFC, the negotiation on the protocol is made using the ALPN protocol. Is there an implementation of ALPN in python 2.7? (I know there are HTTP/2 client implementations, but I want to write it myself) Thanks! 回答1: Please use the documentation and simply search for "alpn". It is well documented, like: SSLContext.set_alpn_protocols(protocols) Specify which protocols the socket should advertise during the SSL/TLS

I went thru this page: https://www.eclipse.org/jetty/documentation/9.3.x/alpn-chapter.html to have an ALPN boot jar in my classpath and still I can't get it working. I am confused as to know if I need an Open SDK Java 8 than Oracle Java 8.

问题 I have returned to JDK8 with Jetty and SPDY and I see that now Jetty 9.2 supports ALPN protocol instead of NPN (see my question How to run Jetty with SPDY on JDK8?). So I set bootclasspath : java -Xbootclasspath/p:c:/jars/alpn-boot/alpn-boot-8.0.0.v2014031 ...
