A CSR or Certificate Signing request is a critical part of attaining an SSL/TLS certificate.
The CSR itself is generated on and used by the same server for which the certificate is intended. It contains information that the Certificate authority (CA) will use to create the certificate for your website, including the common name (domain name), organization name, country, contact details. Alongside a public key, this public key has a corresponding private key, which the CA uses to decrypt and read the information.
