Have An Installer Generate A Private Key And Certificate

Generate CSR - OpenSSL

The certificate is made out of your public key. The public and private keys are completely separate (by definition) and you can't generate one from the other. How was this new.crt file generated? There just has to be a key file and a CSR somewhere! – Alexios Jan 7 '14 at 10:00.

Introduction

This article provides step-by-step instructions for generating a Certificate Signing Request (CSR) in OpenSSL. This is most commonly required for web servers such as Apache HTTP Server and NGINX.

Switch to a working directory

GNU/Linux & Mac OS X users:
Open a terminal and browse to a folder where you would like to generate your keypair

Windows Users:
Navigate to your OpenSSL 'bin' directory and open a command prompt in the same location.

Generate a CSR & Private Key:

openssl req -out CSR.csr -new -newkey rsa:2048 -keyout privatekey.key

To generate a 4096-bit CSR you can replace the rsa:2048 syntax with rsa:4096 as shown below.

openssl req -out CSR.csr -new -newkey rsa:4096 -keyout privatekey.key

Note: You will be prompted to enter a password in order to proceed. Keep this password as you will need it to use the Certificate.

Fill out the following fields as prompted:
Note: The following characters can not be accepted: < > ~ ! @ # $ % ^ * / ( ) ?.,&

Field	Example
Country Name	US (2 Letter Code)
State or Province	New Hampshire (Full State Name)
Locality	Portsmouth (Full City name)
Organization	GMO GlobalSign Inc (Entity's Legal Name)
Organizational Unit	Support (Optional, e.g. a department)
Common Name	www.globalsign.com (Domain or Entity name)

You should now have a Private Key (privatekey.key) which should stay on your computer, and a Certificate Signing Request (CSR.csr), which can be submitted to GlobalSign to sign your public key. Each of these files can be viewed in a plain text editor such as Notepad, TextEdit, Vi, Nano, and Notepad++.

You can also use Microsoft IIS to generate a Private Key and CSR.

4. Next, from the 'Actions' menu (on the right), click on 'Create Certificate Request.' This will open the Request Certificate wizard.

5. In the 'Distinguished Name Properties' window, enter the information as follows:

1. Common Name - The name through which the certificate will be accessed (usually the fully-qualified domain name, e.g., www.domain.com or mail.domain.com).
2. Organization - The legally registered name of your organization/company.
3. Organizational unit - The name of your department within the organization (frequently this entry will be listed as 'IT,' 'Web Security,' or is simply left blank).
4. City/locality - The city in which your organization is located.
5. State/province - The state in which your organization is located.

6. Click Next.
7. In the 'Cryptographic Service Provider Properties' window, leave both settings at their defaults (Microsoft RSA SChannel and 2048) and then click next.

8. Enter a filename for your CSR file.

9. Remember the filename that you choose and the location to which you save it. You will need to open this file as a text file and copy the entire body of it (including the Begin and End Certificate Request tags) into the online order process when prompted

2. Back Up Private Key

To backup a private key on Microsoft IIS 6.0 follow these instructions:

1. From your server, go to Start > Run and enter mmc in the text box. Click on the OK button.
2. From the Microsoft Management Console (MMC) menu bar, select Console > Add/Remove Snap-in.

12. Click on Browse and select a location where you want to save the private key Backup file to and then click Next to continue. By default the file will be saved with a .pfx extension.
13. Click Finish, to complete the export process

3. Convert to RSA Private Key Format

The private key is backed up as a ‘.pfx’ file, which stands for Personal Information Exchange.

To convert it to RSA Private Key format supported by inSync:

1. Download and install latest version of OpenSSL for windows from http://www.slproweb.com/products/Win32OpenSSL.html.

Note: OpenSSL requires Visual C++ 2008 Redistributables which can be downloaded from the same website.

2. Open command prompt, navigate to C:OpenSSL-Win32bin>, and run the following commands.

3. The private key will be saved as ‘myserver.key’.

4. Carefully protect the private key. Be sure to backup the private key, as there is no means to recover it, should it be lost.
