What is a CSR?<\/strong> A CSR or Certificate Signing request is a block of encoded text that is given to a Certificate Authority when applying for an SSL Certificate. It is usually generated on the server where the certificate will be installed and contains information that will be included in the certificate such as the organization name, common name (domain name), locality, and country. It also contains the public key that will be included in the certificate. A private key is usually created at the same time that you create the CSR, making a key pair. A CSR is generally encoded using ASN.1 according to the PKCS #10 specification.<\/span><\/span><\/p>\n

A\u00a0certificate authority<\/a> will use a CSR to create your SSL certificate, but it does not need your private key. You need to keep your private key secret. The certificate created with a particular CSR will only work with the private key that was generated with it. So if you lose the private key, the certificate will no longer work.<\/span><\/span><\/span><\/p>\n

What does a CSR look like?<\/span><\/span><\/h2>\n

Most CSRs are created in the Base-64 encoded PEM format. This format includes the “—–BEGIN CERTIFICATE REQUEST—–” and “—–END CERTIFICATE REQUEST—–” lines at the beginning and end of the CSR. A PEM format CSR can be opened in a text editor and looks like the following example:<\/span><\/span><\/p>\n
