Introduction
The private key is generated simultaneously with the CSR (certificate signing request), containing the domain name, public key and additional contact information. The CSR is to be sent to the certificate authority for validation and signing immediately after the certificate activation in. Oct 25, 2019 Generate RSA private key with certificate in a single command openssl req -x509 -newkey rsa:4096 -sha256 -keyout example.key -out example.crt -subj '/CN=example.com' -days 3650 -passout pass:foobar Generate Certificate Signing Request (CSR) from private key with passphrase. To generate public (e,n) key from the private key using openssl you can use the following command: openssl rsa -in private.pem -out public.pem -pubout To dissect the contents of the private.pem private RSA key generated by the openssl command above run the following (output truncated to labels here).
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.
Strip You can avoid hardcoding the path of the key by using: import os BASEDIR = os. In your production settings file, replace the hardcoded key by: # Use a separate file for the secret key with open ( '/path/to/the/secretkey.txt' ) as f: SECRETKEY = f. Generate django secret key online. Dirname ( os.
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.
