CSR - Certificate Signing Request

This is a file (or actually a string of characters) representing a request from the server to have a certificate signed.

The CSR contains information identifying the requester, such as the domain name, organisation name, location and country, as well as the public key.

The Certificate Authority will issue an SSL certificate based on these details.

The CSR is in plain text and is actually Base64 encoded binary data.
