Creating an OpenSSL Certificate on Windows

Question

Since I am very new to SSL certificates, and also about creating and using them, I decided that StackOverflow members could help me.

I am from Holland, a common way of online payments is to implement iDEAL. Online payment protocol supported by large banks. I have to implement a "professional" version. This includes creating an RSA private key. Based on this key, I have to create a certificate and upload it to the web server.

I am on a windows machine and am completely confused what to do. I looked at the OpenSSL website because the guide sent me to this website to get the SSL Toolkit.

The manual contains two commands that must be completed to create the RSA key and certificate.

Teams:

openssl genrsa -des3 –out priv.pem -passout pass:myPassword 1024

and

openssl req -x509 -new -key priv.pem -passin pass:myPassword -days 3650 -out cert.cer

Is there a way to do this using a utility on a Windows machine? I downloaded PuTTy KeyGenerator. But I'm not sure what to do, I created a key (SSH-2 RSA, whatever that is ..), but how do I create a certificate with this key?

Answer 1

You can download your own OpenSSL for Windows , or you can always use Cygwin .

Answer 2

If you work with windows and use apache, perhaps through WAMP or the Drupal stack installer, you can additionally download git for windows , which includes many useful linux command line tools, one of which is openssl.

The following command creates the self-signed certificate and key required for apache, and works fine in windows:

 openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt 

Answer 3

Using a web application with a certificate, you can easily create a private key and certificate based on it: http://www.cert-depot.com/

He can also create PFX for you.

Answer 4

To create a self-signed certificate in Windows 7 with IIS 6 ...

• Open IIS

• Select your server (top-level item or your computer name)

• In the IIS section, open "Server Certificates"

• Click Create Self-Signed Certificate

• Call it "localhost" (or something like that which is not specific)

• Click OK

Then you can link this certificate to your site ...

• Right-click on your website and select "Change Bindings ..."

• Click Add

  • Type: https
  • IP Address: All Unassigned
  • Port: 443
  • SSL Certificate: "localhost"

• Click OK

• Click Close

Answer 5

You can use putty (puttygen.exe) for this.

Or you can get Cygwin to use the utilities you just described.
