ssl

问题 There are numerous posts on SO about this and I have scoured them, but still don't have a solution. I am hoping that someone can point me in the right direction. We have a requirement now to use TLS 1.2 to connect to a remote provider. So I have installed Windows Server 2016 and configured it as needed: I know the remote server is running TLS 1.2 and that it supports the highlighted cipher. We connect to the remote end point using C# proxy class generated by the WSDL provided by the provider

问题 When trying to compile Python 3.4.3 with gcc (Debian 6.2.1-7) 6.2.1 20161215 I got the following error: Failed to build these modules: _hashlib _ssl When running make again, I got a little more informative output: $ make running build running build_ext INFO: Can't locate Tcl/Tk libs and/or headers building '_ssl' extension gcc -pthread -fPIC -Wno-unused-result -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -Werror=declaration-after-statement -I./Include -I. -IInclude -I/usr/include/x86_64

问题 maybe one of you can help me answer my question about validating certificates in the .NET framework. Unfortunately I found only superficial answers to my questions during my research on the Internet, but no exact explanation. Meanwhile I know that I can check in my software with the following code whether a certificate is valid. ServicePointManager.ServerCertificateValidationCallback += ValidateRemoteCertificate; private bool ValidateRemoteCertificate(object sender, X509Certificate cert,

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 I am working with some code from back in 2003. There is a reference to the following class: new com.sun.net.ssl.internal.ssl.Provider() It is causing an error: Access restriction: The type Provider is not accessible due to restriction on required library /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/jre/lib/jsse.jar Does anyone have any suggestions for a suitable alternative to using this class? 回答1: Most of the time, you don't actually need to create or get hold of a provider

问题 I am trying to run a python urllib2 script and getting this error: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail. For more information, see https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning. After googling the error the solution, on stack overflow is to download requests' security package: pip install requests[security] But when I run that

问题 I have created a secret for my JKS file under volume mount /etc/secrets/keystore. I am accessing my JKS file path as an environment variable where ssl.keystore.location gets resolved as file:///etc/secrets/keystore/ssl.jks. But I get exception from SSL engine builder that modification time of keystore couldn't be found and java.nio.file.NoSuchFile Exception file:/etc/secrets/keystore/ssl.jks 回答1: Remove the file:// . The keystore is opened by the Kafka client, not Spring. Kafka knows nothing
