Before you order an SSL certificate, we recommend you generate a Certificate Signing Request (CSR) from your server or device.
A CSR is an encoded file that provides you with a standardized way to send DigiCert your public key andother identifying information for your company and domain name. When you generate a CSR, most server software asks for the following information: common name (e.g., www.example.com), organization name and location (country, state/province, city/town), key type (typically RSA), and key size (2048-bit minimum).
CSR Generator: DigiCert Certificate Utility
Microsoft Exchange Server
Apache Server (Open SSL)
CSR Generator: Open SSL CSR Wizard
Tomcat Server (Keytool)
CSR Generator: Java Keytool CSR Wizard
Note: To remain secure, SSL certificates must use keys that are 2048-bits in length or greater. If your server platform can't generate a CSR with a 2048-bit key, please contact us. See this article for more information.
