About CSR Generation

When applying for an SSL Certificate, Certificate Signing Request(CSR) is provided to the Certificate Authority (CA) which is a block of encrypted text. Generation of CSR takes place on the server, it stocks information associated with the domain name, organization, city, and country which is supposed to be constituted in the certificate. 


When there is a need to encode information the CSR Certificate can be borrowed from any website. To generate a fresh self-signed SSL certificate, first, you need to generate a CSR certificate. After generating, submit the same to a Certificate Authority (CA) to obtain an SSL Certificate. 


What is a CSR Generation?

CSR Generation is a free online tool that automatically generates your CSR (Certificate Signing Request) and your Private Key, established on the data which you submit in the CSR form. You will require the CSR code while applying for an SSL Certificate. 

The Private Key and CSR code will be sent to you via email for backup purposes so it is advised that you save your CSR code and Private Key as they will be needed when you are installing the SSL Certificate on your server and website. 


There are two types of Certificates:


  1. Self-Signed Certificate: Self-Signed Certificates are Certificates that are signed by the individuality or its private key rather than a trusted certificate authority. These certificates are legal for one year only. If you want to generate an SSL Certificate, the local certificate authority will assist who is in your surroundings which can be later used in the association. It is employed for any locally deployed applications as well as FTP Servers, etc.
  2. CA Authorized Certificate: These certificates are the ones that are handed out from a Trusted Third Party entity wherein they issue the digital certificates. For data encryption, this CA Authorized Certificate is utilized on Internet-facing servers. Based on the plan taken these certificates to hold their validity. Domain Validation is needed to issue CA Certificates.


Features of CSR Generation


Convert Certificate Formats


Most certificates that have been operated with have X.509 certificates that are PEM ASCII encoded. There are many different certificate encoding and container varieties; some applications favor specific formats over the rest. 


Likewise, some of these formats can include numerous items, such as a CA certificate, private key, etc, in one single file. This tool can be used to convert certificates to and from a vast category of these formats. 


 Internet Accessible HTTP Site

With the use of this tool, you can easily get your certificate from any internet-accessible HTTP site. 

If you wish to use HTTPS (HTTP over TLS) to protect your Apache HTTP or Nginx web server, and you wish to use a Certificate Authority (CA) for issuing the SSL certificate, this is a useful technique. The CSR that has been generated can be then sent to a Certificate Authority to propose the issuance of a CA-signed SSL certificate.


 Create Certificate Signing Requests and Private Keys

It should be noted that the CSR does include input about your public key. Only the visitors and users of your website are provided with the Public Key. Whenever a person associates with your website, they will be afforded a new public key to communicate with the private key of your domain. This composes a key pair, which is considered the pillar of modern PKI security.


 Existing Certificate for CSRs Generation

This tool allows you to use the already existing certificates as templates for new CSR generation. Or if you wish to renew an existing certificate but neither you nor your CA has the original CSR due to any reason. It saves you from the hardship of re-entering the CSR input, as it takes out all the required information from the existing certificate.


Get a Sign from Trusted CA

You can use the output to get your CSR signed by a trusted certificate authority (CA). Using a CSR Generation is the best way for you to proceed with the certificate request procedure. Generating and submitting a CSR is the method of formulating the groundwork for an authorized certificate request, the same you will need to forward to a Certificate Authority for issuing the SSL certificates to you.


Support for multiple domains

CSR Generation lets you secure multiple domains with one single certificate. To obtain an SSL certificate that will protect multiple domains, you need to produce a CSR (Certificate Signing Request) and send it to your multi-domain certificate to submit and get the sign from the CA. While generating a certificate for a Multi-Domain SSL certificate signing request, you can make use of your Domain's Common Name (CN) which is also recognized as the FQDN.


Support for Wildcard Certificates

The process of generating a CSR for a wildcard certificate is comparable to a regular CSR wherein the only dissimilarity between the two of them is that an asterisk has to be added without fail before the domain name during the generation process of a CSR for a wildcard certificate. Be certain to utilize the wildcard symbol at the opening to facilitate the wildcard functionality if you want to generate a certificate signing request for a wildcard certificate. 


Supports Many SANs and CNs

CSR Generation allows you to enter as many Common Names (CNs) and Subject Alternative Names (SANs) as you wish. There’s a slight disparity between them. When using the word ‘multi-domain certificates’, it's mainly referred to an SSL certificate that encloses multiple host or domain names. Whereas when the term ‘SAN certificates’ is used, it's presumably referred to a specific certificate that contains any name in the SAN extension.


Generate 2048-bit or 4096-bit keys

2048 is the basic encryption algorithm for the generation of Certificate Signing Request. 2048 bit is completely compatible with all leading Certificate Authorities. Whereas the 4096-bit key is an avant-garde mechanism in the world of encryption technology. Yet, it is more sophisticated and it slows down the process of data transition of the website on the Internet. 2048-bit is the industry standard. It is wise to choose only 4096-bit in case you have specific requirements.


Steps to use CSR Generation 


The below instructions will help guide you through the CSR generation procedure without any confusion. 


  1.  Firstly, log into your server’s terminal.
  2. Enter the Private Key Command and CSR to generate the private key and CSR.
  3. Now, enter your CSR details
  4. Enter the CSR details in the boxes below, when prompted:


a). Common Name: It is also known as FQDN (Fully-Qualified Domain Name) that you wish to conserve along with the certificate.


Make use of the legally registered facts and details of your organization for Business and Extended Validation Certificates. But for Standard Domain Validated Certificates, you must enter your name.


b). Organization: It is the entire legal name of your organization involving the corporate identifier.


c). Organization Unit (OU): It is your unit department such as 'Website Security' or ‘Information Technology.'


d). City or Locality: It's the city or locality where your organization is lawfully incorporated. 


e). State or Province: It's the state or region where your organization is lawfully incorporated. 


f). Country: It is the authorized two-letter country code (i.e. CH, US) where your organization is lawfully incorporated.


g). Email Address: Enter the email address that you've used to generate the certificate. 


  1. Generate the order: Locate and unlock the recently created CSR in a text editor (i.e. Notepad) and copy-paste all the text comprising:
  2. "-----BEGIN CERTIFICATE REQUEST-----" And "-----END CERTIFICATE REQUEST-----" lines. 
  3. You must save this information because you will need this once you have ordered an SSL Certificate to check the generation procedure of SSL designed by the Certificate Authority of your preference. 
  4. The second code which has been generated is your Private Key. Copy the private key in a text editor such as Notepad for safekeeping because you will require to put it on your server once the SSL Certificate installation procedure has begun. Note that you can rename the file as and when needed. 
  5. After the validation process is finished, you will receive an email containing a link to download the certificate. 


Additional Required Steps

Once you have downloaded the certificate, a few extra steps will need to be taken to put together the certificate and its private key so that you can begin with your code signing. If you are utilizing a certificate utility, you might be able to import the "user.crt" file for you to pair it with the key, and also export the Code Signing PFX file from the utility.

If you are using an online tool to generate your CSR, you will have to make use of another online tool to finish creating the Code Signing certificate file.


Few tips for creating a strong CSR

When generating a CSR, there are certain things you can work on to ensure that it is strong and secure:

- It's always advisable to use a 2048-bit key length. 

- Using the SHA256 or SHA512 hashing algorithm strengthens the CSR.

- Make sure to include your domain and company name. 

- Including the organizational unit is always a good idea. 

- Make sure that your private key is well protected with a password. 


Benefits of using CSR Generation

Below are some major reasons why using CSR can be highly beneficial to a user.


Secure your website with an SSL/TLS certificate

Secure Sockets Layer, or an SSL certificate, is a protocol that encrypts transmission between your web server and a user so that a third party does not know about it or impersonates you. As an outcome, your password, credit card number, your login details, and other sensitive data stay safe.


Signing Emails With SSL/TLC Certificate 

You can sign emails with an SSL/TLS certificate using this tool. The route of an email starting from the sender to the directed recipient involves numerous junctures where it can be compromised. The sensitive information by encrypting connections is safeguarded by the SSL/TLC certificate. To receive all-around security when utilizing mail, you will have to make use of the SSL/TLS certificates if you want to secure the entire mail transmission sequence.


Encrypt your files 

If you want to encrypt your files and messages with an SSL/TLS certificate CSR Generation is a suitable tool for it. SSL (Secure Sockets Layer) encryption, and its furthermore modern and secure alternate, TLS (Transport Layer Security) encryption, safeguard data transmitted over the computer network or web. 

This helps avoid attackers as well as Internet Service Providers from viewing or meddling with data traded between two points—typically a user’s net browser and a web/app server. Many website owners and operators should enforce SSL/TLS to conserve the exchange of sensitive information such as payment information, passwords, and other personal information supposedly confidential.


End users


Website Owner


CSR stands for Certificate Signing Request. This is an initial stage that any website owner needs to complete to acquire an SSL Certificate for their domain. The CSR form comprises identification information about the firm owning that domain and the rest of the protected cryptographic information. This information is later borrowed when you obtain an SSL Certificate. The practice of an SSL certificate holds your website secure for your potential customers and users. 




A CSR technique is the basis of the company’s ethical responsibility which strives to endorse and take care of its brand image along with its stakeholders and employees. Functioning on the natural and human aspects are powerful messages to convey to its employees. These efforts will positively impact employees’ dignity and retention. 


Carrying out CSR in your company will bring about a ripple effect of optimistic goods. It helps the company to stand out in the market while performing activities to conserve energy and reduce waste. By performing these actions and different sustainable company strategies, more positivity is brought into society.


Program Developer 


The digital certificate is very significant in the digital society. A digital certificate can be indexed to a computer, user, server, application, or service and can also be indexed to RF access cards. Most people have observed SSL/TLS certificates while they are surfing the web. 


It’s one of the most widespread digital certificates utilized to maintain the communication between a web server (website) and the web browser. But digital certificates are not only employed in ensuring communication over the web, they are also used in verifying the identity of the correlated entity. 


Since digital certificates are not eternal after a limited period they expire. Therefore renewal of the certificate is required. The certificate renewal procedure starts with the generation of a certificate signing request (CSR) and proposals to a Certificate Authority (CA) for a new certificate submitting the Certificate Signing Request (CSR).




CSR initiatives can enhance a customer's faith and public respect. Consumers are more and more sensitive to environmental matters and are impressed with those companies that invest in charitable practice and civil obligation to improve life on our planet. 


Customers are now more inclined to shop for products and services from companies irrespective of their scale, size, or activity, that are socially and environmentally accountable and respectful. This can influence the economic situation, better brand image, and the status of the company once you adopt a CSR policy.


Final Thoughts


CSR Generation is a free tool that permits you to generate CSRs instantly and easily. To generate a CSR, you will require to furnish some information about your organization. This contains the domain name, your organization name, the organizational unit, and some more details. 


The generation of a private key is also a crucial step in the process. This key is employed to encrypt your CSR file. You must keep this key safe and secure as it is required further. After the generation of the CSR, you will be asked to submit it to a Certificate Authority (CA) to obtain a digital certificate. 


CSR (Certificate Signing Request) generation is one of the most important parts of net security, however, it can be a troublesome task to generate a CSR correctly. This tool comes in handy not only to generate a CSR certificate but also to make sure that you have no errors in the existing one, thereby saving you from going through the hardship of correcting it after submission. 


CSR Generation - Related FQAs


Ques: Can I generate my CSR from any server?

Ans: Yes, you can generate your CSR (Certificate Signing Request) from any given server of your choice, but you must know that the SSL/TLS certificate will likewise need to be installed on the same server, as well.


Ques: Will I have to generate a new CSR for certificate renewals, too?

Ans: Yes, you should use a CSR Generation to create a completely new certificate signing request whenever you are in a need to renew your already existing SSL certificates.


Ques: What is a Private Key, and why is it needed?

Ans: A private key is an important element of modern network security, it's a pillar of Public Key Infrastructure (PKI) in it. Namely, it's a cryptographic series that is utilized in pairs with an algorithm to decrypt and encrypt text.


Ques: How to submit my CSR to a Certificate Authority (CA)?

Ans: Once you have generated your CSR (Certificate Signing Request), you can submit it to the CA of your preference. Although CSRs are generated in a universal format, you can contact any SSL provider to use any CSR. The following step without much doubt will be to get in touch with an SSL Provider with your CSR.


Ques: What do you mean by certificate signing?

Ans: An SSL certificate is signed when it has been taken and a look at the information it contains by a trusted third party is verified and legitimized. Signing is the process of finalizing this verification, and it is performed by different Certificate Authorities. Some of the well-known trusted CA are Sectigo, DigiCert, Comoda and GeoTrust.


Ques: Is CSR the same as a private key?

Ans: No. CSR is not the same as a private key, though both of them are technically generated at the exact period when you formulate your CSR in the initial place. All of the information that you provide at the time of the creation of your distinctive CSR (organization unit, organization name, legal name, web server, etc.) is wielded to generate the text file and is used by the CA you choose during the process of verification and signing. This suggests that it furthermore plays a role in generating the private key which you will have to use further.


Ques: Can I generate my CSR from any server?

Ans: Yes. You can use any server to generate your certificate signing request, but then the SSL/TLS certificate too will have to be installed on the same server. For the generation of the certificate signing request, the private key utilize will be from the same server from which you obtain the CSR Generation. Therefore it is ideal to create your CSR while employing the server for your certificate installation.
