Openssl Generate A New Private Key And Certificate Signing Request
A CSR is a file containing your SSL Certificate application information, including your Public Key. Certificate Auto-Requester: We provides a useful tool to automatically create a public/private key pair on your local machine then use this key pair to generate a CSR and automatically submit it to us over a secure SSL connection to create your certificate for Apache. How to create a CSR using openssl A CSR is a Certificate Signing Request and it is the first step of many steps in creating an X.509 certificate. When a CSR is created, the first thing that happens is that a private key is generated which is stored. Reading Time: 3 minutes This guide will walk you through the steps to create a Certificate Signing Request, (CSR for short.) SSL certificates are the industry-standard means of securing web traffic to and from your server, and the first step to getting your own SSL is to generate a CSR.

Introduction
Windows 7 ultimate license key generator. A Certificate Signing Request (CSR) is the first step in setting up an SSL Certificate on your website. SSL certificates are provided by Certificate Authorities (CA), which require a Certificate Signing Request (CSR).
This guide will instruct you on how to generate a Certificate Signing Request using OpenSSL.
- Access to a user account with root or sudo privileges
- A command line/terminal window
- If you’re working on a remote server, an established SSH connection to the server
- OpenSSL needs to be installed on your system to generate the key
- A text editor, such as nano, to view your key
Open a terminal window. Use your SSH connection to log into your remote server.
Note: If you are working locally, you don’t need an SSH connection. Also, most Linux systems will launch a terminal window by pressing Ctrl-Alt-T or Ctrl-Alt-F1.
Step 2: Create an RSA Private Key and CSR
It is advised to issue a new private key each time you generate a CSR. Hence, the steps below instruct on how to generate both the private key and the CSR.
Make sure to replace your_domain with the actual domain you’re generating a CSR for.
The commands are broken out as follows:
- openssl – activates the OpenSSL software
- req – indicates that we want a CSR
- –new –newkey – generate a new key
- rsa:2048 – generate a 2048-bit RSA mathematical key
- –nodes – no DES, meaning do not encrypt the private key in a PKCS#12 file
- –keyout – indicates the domain you’re generating a key for
- –out – specifies the name of the file your CSR will be saved as
Note: Use 2048-bit key pairs. The 4096-bit key pairs are more secure, however, they require a lot more server resources.
Your system should launch a text-based questionnaire for you to fill out.
Enter your information in the fields as follows:
- Country Name – use a 2-letter country code (US for the United States)
- State – the state in which the domain owner is incorporated
- Locality – the city in which the domain owner is incorporated
- Organization name – the legal entity that owns the domain
- Organizational unit name – the name of the department or group in your organization that deals with certificates
- Common name – typically the fully qualified domain name (FQDN), i.e. what the users type in a web browser to navigate to your website
- Email address – the webmaster’s email address
- Challenge password – an optional password for your key pair
Please take into account that Organization Name and Unit Name must not contain the following characters:
< > ~ ! @ # $ % ^ * / ( ) ?.,&
Once the software finishes, you should be able to find the CSR file in your working directory.
You can also enter the following:
The system should list out all certificate signing requests on the system. The one that matches the domain name you provided in Step 2 appended with the .csr extension is the one you need to look into.
Step 5: Submit the CSR as Part of Your SSL Request
You can open the .csr file in a text editor to find the alphanumeric code that was generated.
Enter the following command:
This text can be copied and pasted into a submittal form to request your SSL certificate from a Certificate Authority.
Make sure you copy the entire text. Some CAs may allow you to simply upload the .csr file you generated. Below is an example of a CSR.
You needn’t send the private key to the CA. Once you get your SSL certificate, the private key on the server will bind with it to encrypt communication.
Now you know how to generate an OpenSSL certificate signing request. Before submitting the CSR to a certificate authority, we recommend verifying the information it holds. Use one of the widely available online CSR decoders.
SSL is a crucial protocol for securing traffic between a website and its visitors. It helps to protect sensitive information online, such as credit card data.
Next, You Should Also Read:
A CSR is encoded text that contains information about the certificate requester. This information includes, but is not limited to, the publisher name for the certificate (referred to as a “Common Name”), organization name (if applicable), and a contact email for the certificate. When creating a CSR it will export two files, these two files will be your CSR, which will be requested during enrollment, and a corresponding private key which should not be shared and will be required during installation.
Note: Before proceeding with the instructions below, confirm the Java Development Kit (JDK) is installed correctly on your server or local computer.
The following instructions will guide you through creating a Java Keystore File and CSR. If you already generated the CSR and received your trusted Code Signing Certificate, please click here for Code Signing downloading/exporting Instructions.
1. Run the Keystore prompt
To make a keystore and key file, run the command prompt below:
keytool -genkey -alias server -keyalg RSA -keysize 2048 -keystore keystore.jks

2. Enter the required information, when prompted
- Enter keystore password:
- Re-enter new password:
- What is your first and last name?
- What is the name of your organization unit?
- What is the name of your organization?
- What is the name of your City or Locality?
- What is the name of your State or Province?
- What is the two-letter country code for this unit?
- Is CN = CompanyName or Firstname Lastname, OU=DeparmentName, O=CompanyName, L=City, ST=State, C=CountryCode correct?
- Enter key password for <server>:
The above command will create a Java keystore file called keystore.jks
3. Run the CSR prompt
To make the CSR from the keystore, run the command prompt below:keytool -certreq -alias server -file csr.csr -keystore keystore.jks
Enter keystore password:
Note: The keystore password is the same password you created in step 2.
The above command will create the CSR and private key and saves as a .csr file and a .jks file.
