Mar 30, 2015 Create an RSA Private Key. Creating your private key will require entering the command string itself, the location and file name you wish to use, and the key strength. Type the following command in an open terminal window on your computer to generate your private key using SSL: $ openssl genrsa -out /path/to/wwwservercom.key 2048. In order to prevent the situation when you loose your CSR code and Private Key, we automatically send the CSR code and the Private Key to the email which you provided when using the CSR Generator from above. Please check your email, so as we always send a message from SSL Dragon (email protected) where we include your CSR code and Private Key. Apr 07, 2015 The SSL/TLS protocol uses a pair of keys – one private, one public – to authenticate, secure and manage secure connections. These keys are created together as a pair and work together during the SSL/TLS handshake process (using asymmetric encryption) to set up a secure session. The private key is a text file used initially to generate a Certificate Signing Request (CSR), and later to.

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. If this is not the solution you are looking for, please search for your solution in the search bar above.
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

Csr Vs Private Key
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++.
What is a CSR? A CSR or Certificate Signing request is a block of encoded text that is given to a Certificate Authority when applying for an SSL Certificate. It is usually generated on the server where the certificate will be installed and contains information that will be included in the certificate such as the organization name, common name (domain name), locality, and country. It also contains the public key that will be included in the certificate. A private key is usually created at the same time that you create the CSR, making a key pair. A CSR is generally encoded using ASN.1 according to the PKCS #10 specification.
A certificate authority will use a CSR to create your SSL certificate, but it does not need your private key. You need to keep your private key secret. The certificate created with a particular CSR will only work with the private key that was generated with it. So if you lose the private key, the certificate will no longer work.
What is contained in a CSR?
| Name | Explanation | Examples |
|---|---|---|
| Common Name | The fully qualified domain name (FQDN) of your server. This must match exactly what you type in your web browser or you will receive a name mismatch error. | *.google.com |
| Organization | The legal name of your organization. This should not be abbreviated and should include suffixes such as Inc, Corp, or LLC. | Google Inc. |
| Organizational Unit | The division of your organization handling the certificate. | Information Technology IT Department |
| City/Locality | The city where your organization is located. | Mountain View |
| State/County/Region | The state/region where your organization is located. This shouldn't be abbreviated. | California |
| Country | The two-letter ISO code for the country where your organization is location. | US GB |
| Email address | An email address used to contact your organization. | webmaster@google.com |
| Public Key | The public key that will go into the certificate. | The public key is created automatically |
What does a CSR look like?
Most CSRs are created in the Base-64 encoded PEM format. This format includes the '-----BEGIN CERTIFICATE REQUEST-----' and '-----END CERTIFICATE REQUEST-----' lines at the begining and end of the CSR. A PEM format CSR can be opened in a text editor and looks like the following example:
-----BEGIN CERTIFICATE REQUEST-----

How do I generate a CSR and private key?
You need to generate a CSR and private key on the server that the certificate will be used on. You can find instructions in your server documentation or try the instructions from one of these certificate authorities:
Generate Private Key From Csr
Comodo CSR Generation Instructions
DigiCert CSR Generation Instructions
Entrust CSR Generation Instructions
GeoTrust CSR Generation Instructions
Thawte CSR Generation Instructions
Once you have your CSR generated, you can use our SSL Wizard to find the best SSL certificate that will meet your needs. If you are familiar with OpenSSL you can use the following command to generate a CSR and private key:
openssl req -new -newkey rsa:2048 -nodes -out servername.csr -keyout servername.key
How do I decode a CSR?
You can easily decode your CSR to see what is in it by using our CSR Decoder. In order to decode a CSR on your own machine using OpenSSL, use the following command:
openssl req -in server.csr -noout -text
How To Generate Private Key
What is a CSR/Private Key's bit length?
Openssl Generate Private Key From Csr
The bit-length of a CSR and private key pair determine how easily the key can be cracked using brute force methods. As of 2016, a key size of less than 2048 bits is considered weak and could potentially be broken in a few months or less with enough computing power. If a private key is broken, all the connections initiated with it would be exposed to whomever had the key. The Extended Validation guidelines that SSL certificate providers are required to follow, require that all EV certificates use a 2048-bit key size to ensure their security well into the future. Because of this, most providers encourage 2048-bit keys on all certificates whether they are EV or not.
