问题 A CSR is mainly created to create a certificate having trusted public key. Before creating a CSR, we create a private key openssl genrsa -out key.pem 1024 and then use that private key( key.pem ) to create a CSR( req.pem ) request. openssl req -new -key key.pem -out req.pem Edit: I see that a docker engine is installed with root certificate, server certificate & private used with CSR What is the exact purpose of providing private key( key.pem as input) amidst submitting CSR? Because

问题 I was designing a system where there is a chance of losing the SSL certificate to the attacker. But I am not clear that if the certificate is compromised which all attacks are possible? Man in the middle attack Impersonated attack I want to continue to use SSL certificates to encrypt the communication channel (i.e. prevent man in the middle attack) For authentication I want to send data to predefined end points asynchronously depending on the querying user (Very similar to how we get email

问题 I have a web based application that uses a self signed certificate. When you log into the application, you have to accept the certificate. This is a pain, but..we are OK with that for the time being, and everything is fine. When you click on the help link, it uses java script window.open to open the help in a new window. This all works fine. Except in IE8. In IE8, when I use window.open to open the help file, it again asks the user to accept the SSL certificate. It is like it is in a new

问题 I'm trying to call a REST API for some end point URL, it was running fine for the URL of java.net and after executing the same. But on some machines it failed for some SSLException so the code was modified like this: HttpsURLConnection connection = (HttpsURLConnection) new URL( url ).openConnection() SSLContext sc = SSLContext.getInstance("TLSv1.2") sc.init(null, null, new SecureRandom()) connection.setSSLSocketFactory(sc.getSocketFactory()) connection.setRequestProperty("charset", "utf-8")

问题 I making a call to get using JsonServiceClient to serialize my request object. My server is using https and I created a self signed certificate.

In a browser I can ignore this message. How can I get the JsonService client to work with https and a self signed certificate? 回答1: I think this is a

问题 I keep seeing disjointed accounts all over the web of what the .cer file is and how to generate it so that the app can properly communicate with the server via https. To quote this source, one person says: 1) You now need .cer files in your bundle for all certificates in the chain. So, at least, two certificate files must be present (your certificate and the root CA). In our case, we needed an intermediate as well. 2) These certificates must be in a particular order. Specifically, the
