What is a Certificate Signing Request (CSR)?

A CSR is a block of text that contains information about your organization and your website. It is generated by your web server and used to request a digital certificate from a Certificate Authority (CA). A CSR typically includes:

- The common name (e.g. or email address you are requesting the certificate for
- Your organization's name
- The organizational unit (e.g. IT, Marketing, etc.)
- Your city or locality
- Your state or province
- Your country
- A 2048-bit key size

How to generate a CSR

A certificate signing request (CSR) is a block of text that contains information about your company and your website. This block of text is then used to generate a corresponding private key and public key, which are used to secure your website.

To generate a CSR, you will need to use a tool like our Online Check CSR Tool. This tool will prompt you for the information needed to generate a CSR, and then it will generate the CSR for you.

Once you have your CSR, you can then submit it to a Certificate Authority (CA) to get your SSL certificate.

Why use an Online Check CSR Tool?

If you're looking to verify that a Certificate Signing Request (CSR) was generated correctly, an Online Check CSR Tool can be a helpful tool. Here's a look at why you might want to use one of these tools and how they work.

When you generate a CSR, you're creating a public/private key pair that will be used to create your SSL certificate. The public key is embedded in the CSR, while the private key remains safely on your server.

If there are any errors in the CSR - for example, if the wrong information was entered or if the keys were generated incorrectly - then the resulting SSL certificate will be invalid. That's why it's important to verify the CSR before submitting it to a Certificate Authority (CA) for signing.

An Online Check CSR Tool allows you to check for common errors in a CSR. Simply enter the CSR into the tool and it will analyze it for mistakes. This can save you time and frustration by catching errors early on, before you've submitted the CSR to a CA.

The Online Check CSR Tool also shows you the contents of your CSR, including your public key. This can be helpful in verifying that all of the correct information was entered when the CSR was generated. You can also use this tool to view your private key (though it is generally not recommended to share your private key with anyone).
