Enable secure protocols, configure strong cipher suites, and implement HTTP Strict Transport Security (HSTS).<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"certificate-signing-request\">What is a Certificate Signing Request?<\/h4>\n\n\n\n<p>A Certificate Signing Request (CSR) is a file that includes your website&#8217;s public key and other important information about your company and its domain. This kind of file serves as a formal request to a Certificate Authority (CA) for the issuance of an <a href=\"https:\/\/www.hosted.com\/security\/domain-validated-ssl-certificates\" alt=\"Link to Hosted.com Website - DV SSL Certificates\" title=\"Hosted.com - DV SSL Certificates\" target=\"_blank\" rel=\"noopener\">SSL cert<\/a>i<a href=\"https:\/\/www.hosted.com\/security\/domain-validated-ssl-certificates\" alt=\"Link to Hosted.com Website - DV SSL Certificates\" title=\"Hosted.com - DV SSL Certificates\" target=\"_blank\" rel=\"noopener\">ficate<\/a>. Before you can install an SSL certificate on your server, you must generate and submit a CSR to the CA, ensuring that your website&#8217;s identity and ownership are verified.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"significance-of-csr\">The Significance of a CSR<\/h4>\n\n\n\n<p>CSRs serve as a mechanism for requesting SSL\/TLS certificates, which are essential for establishing trust, encrypting communication, and enhancing the security of websites and online transactions.&nbsp;<\/p>\n\n\n\n<p>They also encode the public key of an entity such as a website or server, along with relevant identification information. This data is securely transmitted to a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Certificate_authority\" alt=\"Link to Wikipedia - Certificate Authority\" title=\"Wikipedia - Certificate Authority\" target=\"_blank\" rel=\"noopener\"> Certificate Authority (CA)<\/a> to request the issuance of an SSL\/TLS certificate.<\/p>\n\n\n\n<p>Other information included in a Certificate Signing Request CSR are about the organization or individual requesting the certificate, helping CAs verify domain ownership and confirm the legitimacy of the certificate request.<\/p>\n\n\n\n<p>Certificate Signing Requests play a crucial role in establishing trust between users and websites. By obtaining SSL\/TLS certificates based on valid CSRs, websites can demonstrate their authenticity and assure users that their connections are secure.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"prerequisites-for-generating-csr\">Prerequisites For Generating a CSR<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Organization Name<\/li>\n\n\n\n<li>Location of the Organization<\/li>\n\n\n\n<li>Key Type and Size (the minimum is 2048-bit)<\/li>\n\n\n\n<li>Common Name (EXAMPLE:www.example.com)<\/li>\n<\/ul>\n\n\n\n<p class=\"has-vivid-red-color has-text-color has-link-color wp-elements-71ff36e9aaaa7a4998f2e727b722c886\"><strong>IMPORTANT:<\/strong><\/p>\n\n\n\n<p class=\"has-vivid-red-color has-text-color has-link-color wp-elements-1d3040b283558242a2de2ec13a741119\">If you are generating a CSR for a Wildcard SSL (for sub-domains) \u2013 the common name must start with an asterisk, which assumes any name excluding a dot-character (EXAMPLE:*example.com).<\/p>\n\n\n\n<p>When configuring your SSL Certificates, the generated CSR will need to be pasted into the order form.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"general\">General Information About CSRs and SSLs<\/h4>\n\n\n\n<p>When generating the CSR, it&#8217;s important to choose an appropriate encryption strength for the private key. A 2048-bit RSA key is commonly recommended for strong security, but you may opt for higher strengths like 3072-bit or 4096-bit for enhanced protection.<\/p>\n\n\n\n<p>Ensure that the CSR includes accurate information that will remain valid for the duration of the SSL certificate.<\/p>\n\n\n\n<p>If your website requires SSL certificates for multiple subdomains or multiple domains, consider using wildcard or multi-domain certificates. These require additional configuration when generating the CSR to include all relevant domains.<\/p>\n\n\n\n<p>In the event of compromised security or changes to your organization&#8217;s information, you may need to revoke or renew your SSL certificate. Understand the process for updating CSRs and obtaining new certificates from your CA.<\/p>\n\n\n\n<p>Safeguard the CSR and private key by securely backing them up. Losing these files could complicate certificate installation or lead to security vulnerabilities. Store backups in encrypted formats and restrict access to authorized personnel only.<\/p>\n\n\n\n<p>Depending on your industry and geographical location, you may need to comply with specific regulations or standards regarding SSL certificate issuance and management. Familiarize yourself with relevant requirements to ensure compliance.<\/p>\n\n\n\n<p>After installing the SSL certificate, review and configure your server&#8217;s SSL settings to maximize security. This includes enabling protocols like TLS, configuring cipher suites, and implementing HTTP Strict Transport Security (HSTS) for enhanced protection against attacks.<\/p>\n<\/div>              <div id=\"eckb-article-content-footer\"><div class=\"eckb-article-content-footer__article-meta\"><div class=\"eckb-ach__article-meta__views_counter\"><span class=\"eckb-ach__article-meta__views_counter-icon epkbfa epkbfa-signal\"><\/span><span class=\"eckb-ach__article-meta__views_counter__text\">Views<\/span><span class=\"eckb-ach__article-meta__views_counter__name\">529<\/span><\/div><\/div>\r\n\t\t<section id=\"eprf-article-buttons-container\" class=\"eprf-rating-mode-like-dislike eprf-afc--reset\">\t\t\t\r\n\t<div\r\n\t\t\tclass=\"eprf-like-dislike-module eprf-like-dislike-module--layout-1 \">\r\n\r\n\t\t<div class=\"eprf-like-dislike-module__text\"  style=\"color: #003e71;

Before you can install an SSL Certificate on your server, you must generate a Certificate Signing Request (CSR). A CSR is required by the Certificate Authority (CA) to validate your website\u2019s identity and ownership before issuing the SSL\/TLS certificate. At Hosted.com\u00ae, we aim to make this process simple and secure. Our Support Team can generate a CSR for you, or you can create one yourself on your server.
