How to install a ssl sertificate from diffrent server to my server, - ssl

Question

I want to create a website in my IIS server, (website already has ssl certificate).
So i created a site, I have the certificate details which contains certificate, private key , CA certificate (all in one text file).
I havent created a csr request for this, But i need to install this certififcate in my system.
When i followed the steps in complete cerififcate request, first it got added, but when i refresh and came back it was gone.
Please help me how to install certififcate from other server, without creating csr request.?
i have:
1)Certificate:
2)Private key (.key)
3)CA certificate (-ca.crt)
in the text file.

Answer 1

You can do this with just built-in tool certutil.exe which is shipped with every Windows installation.
make sure SSL certificate file and private key file are stored in the same folder and have same name: mycert.cer and mycert.key, for example. Certificate will have .cer file extension, key file will have .key file extension.
run the following command: certutil -mergepfx path\mycert.cer path\mycert.pfx
this command will merge SSL certificate and private key into PFX container. Enter password when prompted.

Answer 2

You need to convert the text file into *.pfx file so that you can import it on IIS
Open the .key via notepad copy the content and save it in a new notepad say abc.txt
-----BEGIN PRIVATE KEY-----

-----END PRIVATE KEY-----
Now open the certificate via notepad copy the content and paste it in the same abc.txt notepad
-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----
Open the -ca.crt via notepad copy the content and paste it in the same abc.txt file (this file will contain intermediate and root certificates)
-----BEGIN CERTIFICATE-----

At the end, your abc.txt file will have something like this

Download OpenSSL from here
Ones installed copy the abc.txt and paste it in the bin path of OpenSSL (e.g. C:\OpenSSL\bin)
Open the CMD, change directory to the bin folder of OpenSSL and paste the below command in CMD
openssl pkcs12 -export -in abc.txt -out xyz.pfx
give any password
You can use the xyz.pfx to import on IIS by using the same set of password
