CSR

The CSR (Certificate Signing Request) is an encrypted file that contains the public key, location and URL (Web address) of the company.

To create a CSR, you must use the Web server software. When generating CSR, the Web server creates two files: a private key and CSR.

The CSR is required when the client asks a server ID. The CSR has to be sent to us together with the application of server certificate.

Before you start the request to issue an SSL certificate, you must ensure that you already have the CSR.

When generating the CSR, most server software requests the following information: common name (por exemplo, www.example.com), organization name and location (country, state/province, city/town), key type (typically RSA), and key size (minimum 2048 bits).

Below you will find the instructions for the main servers. For other servers you can consult this help.
