In general terms, the server generating the CSR generates a key pair (public and private). It then uses the private key to pack up the requested information (including the public key) and sends it off to be signed, keeping the private key in a separate location. What I am trying to do is, create a CSR and with a private key that is password protected (the key). In OpenSSL I can create a private key with a password like so: openssl genrsa -des3 -out privkey.pem 2048 Is there some way I can use the key I just created and generate a CSR using the key? Sep 11, 2018 You apply by generating a CSR with a key pair on your server that would, ideally, hold the SSL certificate. The CSR contains crucial organization details which the CA verifies. Generate a CSR and key pair locally on your server. The key pair consists of a public and private key.
The private key is not being encrypted, but just used to encrypt CSR's info. @Armin In the question the command openssl req -newkey rsa:2048 -keyout my.key -out my.csr will both generate a private key and use it to sign a CSR. OpenSSL, by default, prompts for a password and uses that to encrypt the private key on disk.
For those of you who are new to SSL, or even you veterans who just want to brush up on your knowledge, we’re starting a series on SSL basics. First up are certificate signing requests (CSRs). These little files are a critical part of applying for an SSL Certificate, but what are they exactly and how can you generate one?
How to generate private key and CSR from command line. This article describes how to generate a private key and CSR (Certificate Signing Request) from the command line. You may need to do this if you want to obtain an SSL certificate for a system that does not include cPanel access, such as a dedicated server or unmanaged VPS. Jul 09, 2019 The private key gets generated along with your Certificate Signing Request (CSR). The CSR is submitted to the certificate authority right after you activate your certificate, while the private key must be kept safe and secret on your server or device. Later on, this key is used for installation of your certificate.
A certificate signing request (CSR) is one of the first steps towards getting your own SSL Certificate. Generated on the same server you plan to install the certificate on, the CSR contains information (e.g. common name, organization, country) the Certificate Authority (CA) will use to create your certificate. It also contains the public key that will be included in your certificate and is signed with the corresponding private key. We’ll go into more details on the roles of these keys below.
The CA will use the data from the CSR to build your SSL Certificate. The key pieces of information include the following.
1. Information about your business and the website you’re trying to equip with SSL, including:
| Common Name (CN) (e.g. *.example.com www.example.com mail.example.com) | The fully qualified domain name (FQDN) of your server. |
| Organization (O) | The legal name of your organization. Do not abbreviate and include any suffixes, such as Inc., Corp., or LLC. For EV and OV SSL Certificates, this information is verified by the CA and included in the certificate. |
| Organizational Unit (OU) | The division of your organization handling the certificate. |
| City/Locality (L) | The city where your organization is located. This shouldn’t be abbreviated. |
| State/County/Region (S) | The state/region where your organization is located. This shouldn't be abbreviated. |
| Country (C) | The two-letter code for the country where your organization is located. |
| Email Address | An email address used to contact your organization. |
2. The public key that will be included in the certificate. SSL uses public-key, or asymmetric, cryptography to encrypt transmitted data during an SSL session. Online malwarebytes license key generator. The public key is used to encrypt and the corresponding private key is used to decrypt.
3. Information about the key type and length. The most common key size is RSA 2048, but some CAs support larger key sizes (e.g. RSA 4096+) or ECC keys.
The CSR itself is usually created in a Base-64 based PEM format. You can open the CSR file using a simple text editor and it will look like the sample below. You must include the header and footer (-----BEGIN NEW CERTIFICATE REQUEST-----) when pasting the CSR.

Generating the CSR will depend on the platform you’re using. We have a number of support articles with step-by-step instructions for doing this in the most popular platforms, including cPanel, Exchange, IIS, Java Keytool and OpenSSL. You can find them here.

The following instructions will guide you through the CSR generation process on Nginx (OpenSSL). To learn more about CSRs and the importance of your private key, reference our Overview of Certificate Signing Request article. If you already generated the CSR and received your trusted SSL certificate, reference our SSL Installation Instructions and disregard the steps below.
1. Log in to your server’s terminal.
You will want to log in via Secure Shell (SSH).
2. Enter CSR and Private Key command
Generate a private key and CSR by running the following command:
Here is the plain text version to copy and paste into your terminal:
Note:Replace “server ” with the domain name you intend to secure.
3. Enter your CSR details
Enter the following CSR details when prompted:
- Common Name: The FQDN (fully-qualified domain name) you want to secure with the certificate such as www.google.com, secure.website.org, *.domain.net, etc.
- Organization: The full legal name of your organization including the corporate identifier.
- Organization Unit (OU): Your department such as ‘Information Technology’ or ‘Website Security.’
- City or Locality: The locality or city where your organization is legally incorporated. Do not abbreviate.
- State or Province: The state or province where your organization is legally incorporated. Do not abbreviate.
- Country: The official two-letter country code (i.e. US, CH) where your organization is legally incorporated.
Note: You are not required to enter a password or passphrase. This optional field is for applying additional security to your key pair.
4. Generate the order
Locate and open the newly created CSR in a text editor such as Notepad and copy all the text including:
Note 1: Your CSR should be saved in the same user directory that you SSH into unless otherwise specified by you.
Note 2: We recommend saving or backing up your newly generate “.key ” file as this will be required later during the installation process.

Upon generating your CSR, your order will enter the validation process with the issuing Certificate Authority (CA) and require the certificate requester to complete some form of validation depending on the certificate purchased. For information regarding the different levels of the validation process and how to satisfy the industry requirements, reference our validation articles.
After you complete the validation process and receive the trusted SSL Certificate from the issuing Certificate Authority (CA), proceed with the next step using our SSL Installation Instructions for Nginx using OpenSSL.
