tls1.2

问题 We have recently upgraded our Java version to JDK 1.8.0_141 which is forcing our java client to use TLS 1.2 and we have a .Net 2.0 web service running on a Windows Server 2008 SP2 which supports only SSL V3 and TLS 1.0 OS Name: Microsoft Windows Server 2008 Standard OS Version: 6.0.6002 Service Pack 2 Build 6002 So I've applied the patch (Update for Windows Server 2008 (KB4019276)) from below KB to enable TLS 1.1 and TLS 1.2 https://support.microsoft.com/en-us/help/4019276/update-to-add

问题 In Live server we have perl version 5.6.1 ,recently we have enabled TLS 1.2 which resulted in a error " 500 SSL Negotiation failed ". Earlier we have TLS 1.0 we don't have any issues. Enabling TLS 1.2 is unavoidable which is mandatory. How to resolve this issue? I have searched & found that SOAP-LITE module has to be installed in order to resolve the above issue but the version 5.6.1 does not support SOAP-LITE module. It is available in active perl 5.8 and above version. Is it adviseable to

问题 Recently deployed a Windows 2016 Standard Server, with Active Directory and Exchange 2016. We have disabled SSL 1.0, 2.0 and 3.0 for both Server and Client, and have disabled TLS 1.0 and TLS 1.1. We are repeatedly getting the following entry in our system log. What is causing this, and how can I fix it. 回答1: Basically we had to enable TLS 1.2 for .NET 4.x . Making this registry changed worked for me, and stopped the event log filling up with the Schannel error. More information on the answer

问题 I am trying to extract TLS meta-data from a pcap using Scapy. I am able to successfully parse the packets and individual messages such as the client-hello, server-hello etc and their fields. What I am having trouble with is when the TLS record is spread across multiple TCP packets/segments. This happens mostly for large TLS messages, such as application data or when server sends multiple TLS messages (server hello, certificate, etc) in one TLS frame. In such cases, scapy says it has the TLS

问题 Is there a command to check the TLS version reuired by a host site. Right now, the only way I know to check is by adjusting the max TLS version of my browser and checking if I can still access the site. However, I suspect there is a more sophisticated way to do this. 回答1: you can check using following commands for tls 1.2 openssl s_client -connect www.google.com:443 -tls1_2 for tls 1.1 openssl s_client -connect www.google.com:443 -tls1_1 for tls 1 openssl s_client -connect www.google.com:443

问题 I am reading the documentation for both push using TLS certificates and push using authentication tokens But besides explaining how to configure each, the articles don't really explain the differences or pros/cons of both approaches. Can somebody explain them to me? 回答1: Token-based authentication is newer and essentially simplifies APNS authentication. It is based on a public and private key pair that you can generate on your Apple developer account. Here are the main reasons why it is
