   I am able to successfully compile the code but when i Run The sample test that are part of sample project i get an Exception "Could not create SSL/TLS secure channel."  I have created Certificate and downloaded Key's as mentioned in readme file of sample project.

    Following is my APP.Config file setting's. I have put dummy userid and password in this post but in my solution I have got them from my Dashboard.

    Attached i the screenshot of my commands i have used to create certificate file. And also the exception Message i am getting.

Not sure what am I missing. Any help is appreciable.

Hello,

Thanks for being a Visa Developer Community contributor every time you post questions and solutions in the forum! 

To resolve the error, can you please create a new .p12 using the command line below.

Command line: openssl pkcs12 -export -out p12certfile.p12 -inkey example-key.pem -in cert.pem

After that, please try to call the helloworld method and see if you get a succesful response. If the error persists, please let me know what API you were trying to call and share your request header and snapshots of the error. 

Sincerely,

Diana

Hi Diana,

    I am not sure where is "Hello World" method. I have created a certificate using the command you have suggested but hte errors is still the same. I am not sure if i am missing something on my machine to configure TLS 1.2. I checked in registry i didn't find any entry for them. 

   The issue i am having is very basic. is there any prerequist's security settings that are required for the first time API user's. ? Or  do i need to Add  specific API's in my Dashboard before i can use them. 

Attached is the my Header and Command that i have used for creating certificate.

Hi,

Thanks for helping the Visa Developer Community every time you post questions and solutions to this forum! Are you still seeing the issue? I tooked a look at the image you attached to the community forum post and there are some edits that you should do (refer to Image 1). Here is how you can regenerate the .p12 file using the below command. You'll need to replace the 'Example' word with the file name (e.g. Example.p12 and key_Example.pem).

openssl pkcs12 -export -out Example.p12 -inkey key_Example.pem -in cert.pem

Hi Diana,

    Thanks a ton for your reply. As suggest in your previouse post i followed the Getting started guide and Tested my Keystore,Usieid and password using SOAPUI and tested there validation with Helloworld API Call. It was successful. My Samll Win. 

    This means my Credentials are fine. I have used the same file App.Config file and still have the same issue with C# Sample code. 

   To take step further i downloaded a sample code for NODE.JS and i was able to run that sample code with success. 

   I want to use C# as my platform for development and i am not able to run that sample successfuly. 

   Can you please try the C# Sample on your machine and see if you have the same error. 

You help on this is Highly appriciated. 

Thanks
