I am working on HTTPS calls in jmeter. When I started to do the configuration I took help of stackoverflow. Surprisingly I found all I have to do is to change protocol from HTTP to HTTPS and it actually worked. Which makes me wonder how jmeter bypasses the certificate without any configuration?
Some sites use simple mode of HTTPS which doesn't require client installation
SSL and TLS encryption can be configured in two modes: simple and mutual. In simple mode, authentication is only performed by the server. The mutual version requires the user to install a personal client certificate in the web browser for user authentication.
As per 1.2.4 SSL Encryption chapter:
The JMeter HTTP samplers are configured to accept all certificates, whether trusted or not, regardless of validity periods, etc. This is to allow the maximum flexibility in testing servers.
If the server requires a client certificate, this can be provided.

Hi I am integrating the Jmeter with the opeshift pipeline using Jenkins to test my API(https). When the Jmeter is trying to send the request to the API I am getting following error:
Non HTTP response code: javax.net.ssl.SSLHandshakeException - Non HTTP response message: java.security.cert.CertificateException: No name matching <> found
I have tried steps to ignore the SSL certificate verification but I am unable to bypass the process.
I have created a spring boot project to run the load test as a pipeline. I am using <groupId>com.lazerycode.jmeter</groupId> and using the the jmeter file with extension .jmx to run in jenkins.
As per SSL Encryption chapter of JMeter Documentation:
The JMeter HTTP samplers are configured to accept all certificates, whether trusted or not, regardless of validity periods, etc. This is to allow the maximum flexibility in testing servers.
If the server requires a client certificate, this can be provided.
So by default JMeter will trust all certificates no matter of their validity, incomplete chain, subject not matching dns hostname, etc.
If might be the case that your application requires JMeter to send client certificate for security reasons, it can be done either using SSL Manager or providing the relevant system properties pointing to the keystore where the certificate lives.

I'm unable to record login functionality every time its giving validation message on login screen with proxy on. On removing the proxy login functionality works fine. I'm using localhost with port given with the URL of the system under test.
Address is something like - 52.xxx.xxx.xxx: Portnumber
Please help..!!
It may be connected with HTTPS protocol, sending username and password in plain text is a very bad practice so I am more than sure your application is using some form of TLS encryption.
JMeter is able to decrypt and record secure traffic, however some extra configuration will be required, in particular you will need to add JMeter's self-signed certificate into browser so JMeter would be able to intercept secure traffic. Pay attention to the following chapters of the JMeter's HTTP(S) Test Script Recorder documentation:
HTTPS recording and certificates
Installing the JMeter CA certificate for HTTPS recording
If you will be still experiencing problems check out Recording HTTPS Traffic with JMeter's Proxy Server article for troubleshooting steps.
I have been working with web services connecting to URLs provided by different clients and so far it has all been done using one-way authentication. Now I'm asked to enable 2-way (mutual) authentication for one of the clients. I did a lot of research and reading but still confused about a lot of things.
I could test successfully on my local machine following instructions from various different articles. But the problem is now to deploy it in production.
Here's what I did for testing: I created a test Web service Host and assigned it a self-signed certificate and created a client to test this. After this I created a client certificate using makecert and verified that this is installed via MMC. I then modified my Host app to only allow clients with certificate and tested from client to see the connection refused due to not providing the client certificate. Then I modified the bindings in the client application to include the certificate name and I was able to connect to the Host successfully. So this completes local hosting.
Now the real problem. The tech team is going to create a certificate in "cert store" on the server. And I need to test again to make sure everything works as expected. We have a few different developers who all want to test on their machines on their local code. Can we all use the same certificate somehow? I don't think we would be allowed to import the certificate but what suggestions could I give them so all of us can use the same certificate?
I'm also confused about issues like difference between windows certificate and IIS certificate. What advantages would the IIS certificate provide?
Thanks for help!
Edit: Could one of the differences between installing on IIS be so that the hosted sites be accessed via SSL connection? This would mean we don't really need to install on IIS if it's just a client certificate. Is this correct?

When i am trying to record https urls with jmeter, i am getting below message in log:
jmeter.protocol.http.proxy.Proxy: [64432] Empty response to http over SSL. Probably waiting for user to authorize the certificate for XXXXXXX:443.
Its not loading any pages of our application.
Can anyone please help me how to resolve this issue?Thanks

Among resolutions for your issue:
Install in the browser as described in documentation the Fake Certification Authority created by JMeter
Call https URL in the browser and accept certificate, then start recording your scenario
Have you added JMeter's self-signed certificate to browser's exception list?
If so - try removing the certificate and starting over.
For other troubleshooting options and recommendations see Recording HTTPS Traffic with JMeter's Proxy Server guide.
I suggest using SmartMeter Recorder. You will avoid all isues with setting up the proxy. SmartMeter Recorder uses its own Chrome plugin and works out of the box. Read the article for more info.
First of all for performance testing you should have application setup without the certificates otherwise you are testing results will differ. Your objective should be to test actual calls and those should be isolated.
If you still insist doing with certificate then you need to register JMeter certificate with browser which you are using for recording. You can find that in JMeter bin directory. Just register with your browser which you are using fir recording.
I am planning to implement a small standalone program that will make a https request to a server. Does that require a valid ssl certificate in the client? How does the SSL handshake work in that case? Are there any security issues in the client not have an SSL certificate?
Apart from encrypting the network traffic, HTTPS is normally used to authenticate the server. That is, to give clients reassuring information about who owns the server, etc. For that to work, the client needs to inspect the trust chain in the certificate published by the server. For that to happen automatically, the client machine should have a certificate installed that describes a Certification Authority that issued the server's certificate. Normally such certificates are found on your machine in a store called "Trusted Root Certification Authorities" and most OS come with a set of common CAs already installed.
In addition, many web servers offer a feature where the client can authenticate itself to the server by supplying a client certificate. The web server is able to inspect the certificate coming from the client and map it onto a set of permissions on the server. This "client authentication" is not necessary for a working HTTPS session however, it's just an option.
In short, you don't actually need any certificate on the client, but you will probably want to have a root CA certificate in order to validate the server's identity. If you don't have that certificate it will be impossible for you to trust the server (unless you have another good reason to do so), but you might choose to exchange data with it anyway.
If you wish to learn more about the HTTPS handshake and what is negotiated, i fully recommend you look at this excellent write up at moserware

A client certificate is required only if the server requires one. A client certificate allows the server to authenticate the client, but this is only useful if the server has a list of all authorized clients. That's generally not the case with a web server, so it's quite rare for them to require client certificates.
When present, the client-side certificate does not affect establishment of the secure channel. (Only the server's certificate is required for that and adding a client certificate into the mix doesn't change the process.) Once a secure channel is established, the server will use the client's certificate the authenticate the client (generally by comparing the client's public key or name with a list of authorized clients).
You dont need a certificate to make a HTTPS connection, but you do need to if you want to know with whom you are communicating.
