FTPS Certificate Information

The TLS/SSL certificate used for FTPS is the same certificate that is used for your Files.com site's web portal. This applies to both implicit (port 990) and explicit (port 21) versions of FTPS. The certificate is updated and renewed automatically every 3 months, making it impractical to provide a documented fingerprint as it changes so frequently.

Our TLS/SSL certificates are always valid and fully chained. Your FTPS client will automatically verify the validity of certificates for you and will prompt you if an invalid certificate is found when making a connection.

If you want to verify a certificate's validity yourself then you can check the certificate by using an online SSL Checker, and pointing it at your Files.com site.

If you are using the Custom Domain feature, and are providing your own TLS/SSL certificate for your site, then the certificate you provided will be used for FTPS instead.

FTP client apps will check the fully qualified domain name (FQDN) of the presented TLS/SSL certificate against the name of the FTP site that is being connected to. If they do not match then the client will inform the user that this connection might not be secure. Make sure your FTP users are connecting to the same fully qualified domain name (FQDN) as defined in your TLS/SSL certificate.
