CSR

  • What is a 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.

     

  • How to create a CSR?

    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.
