CSR Request Decoding Tool

Use our free online CSR request decoding tool to make sure your CSR code is correct and can be used to order an SSL certificate.

All you need to do is copy your CSR request into the text box below.

The correct CSR code must:
start with '-----BEGIN CERTIFICATE REQUEST-----'
and end with '-----END CERTIFICATE REQUEST-----'.

Once the CSR request is decoded, you will see the following fields: Organization, Division, Common Name, State/Region, Email Address, Country and other technical details. If errors occur during the decoding process, we recommend that you recreate the CSR request.

Paste a CSR request to decode

A free online CSR decoder tool is used to decode a request. It allows you to verify the correctness of the request and also to see what is specified in the request. When ordering a certificate on Regery, you do not need to specify a CSR request; the system will create it automatically if necessary.

How the CSR decoder works

Decoding a CSR on the site is free of charge. Customers who decide to buy SSL will be allocated secure online storage for keys, SSL certificates and CSR requests. Everything can be quickly restored if needed, with no need to order a reissue.

The request decoded by the decoder contains data such as:

  • company name or the full name of an individual;
  • region, country;
  • name of the department involved in the acquisition;
  • email.

The online CSR decoder works very quickly. A correctly formed CSR will start with the line -----BEGIN CERTIFICATE REQUEST----- and end with the line -----END CERTIFICATE REQUEST-----. To start decoding, you must paste the CSR request into the field and click the "Decode CSR code" button.

How to generate a request

If you need to generate a CSR request, you can use a simple and free CSR generator.

When purchasing a certificate for a subdomain, you should specify its full name in this form: subdomain.domain.com. It is important to take into account the peculiarities of the purchased product. If it is a wildcard certificate, it covers one site and all its first-level subdomains. In this case, for such a certificate protecting subdomains, you will need to specify the [*] sign, for example: *.domain.com.

Buyers of a multi-domain product should specify the main domain and add the additional domains to the list. The site name is written in full. Subdomains can be added later when configuring the certificate.

If you ask for help from specialists, you can create a correct CSR request quickly and without errors. Many people have a hard time figuring out how to fill out the form correctly. If you have questions about what an SSL certificate is, how to create a key or how CSR decoding is done, you should contact support.
