A Certificate Signing Request (CSR) is a file that an SSL issuer uses to request an SSL certificate from a certificate authority (CA). The organization making the request provides information in the CSR, including the organization name, domain names the user wishes to secure, key algorithm type, and key size. When a CA issues an SSL based on a CSR, they essentially sign the public key and domain names in that CSR, digitally binding them to the certificate.
The importance of an adequately generated CSR for an SSL certificate lies in ensuring the accuracy and legitimacy of the SSL. The information included in the CSR must match the information that the issued SSL certificate will contain. Any discrepancies can cause SSL validation errors and warnings in browsers. A correctly generated CSR also proves that the requester controls the domain names listed in the request. They have the corresponding private key, which helps prevent fraudulent SSL certificate requests and issuances.
The CSR specifies the details of the SSL certificate & demonstrates that the issuer has control over the domains. By generating an accurate CSR, organizations can ensure the resulting SSL certificate is accurate, trusted, and accepted by browsers. It helps establish a secure connection for users visiting their websites. A proper CSR is essential to obtaining a trusted and functioning SSL certificate.
