A '''Certificate Signing Request''' ('''CSR''') is a file that contains a public key, along with some metadata which typically includes an organization name, domain name, etc.

A CSR file is intended to be sent to a certificate authority, who can then (after performing any required validation of the sender's identity) generate and send back a signed [[X.509 certificate|certificate]]. Note that the certificate authority does not need to know the certificate's [[RSA private key|private key]].

The most common CSR format is [[PKCS10]].
