 +# SSL CN
  
 +The Common Name - CN - identifies a [hostname](/​glossary/​h/​hostname) associated with an [SSL](/​glossary/​s/​ssl) server [certificate](/​glossary/​s/​ssl_certificate).
 +
 +The certificate is valid for a request only if the requested hostname matches the certificate common name.
 +
 +For a single-name certificate,​ the common name is a single hostname (`example.com` or `www.example.com`).
 +
 +For a wildcard certificate,​ the common name is a wildcard name (`*.example.com`).
