GlobalSCAPE Secure FTP Server includes a utility that allows you to sign certificate requests created by other clients. Typically you sign a client certificate request with the certificate you created for your server. If you use a certificate from your FTP server's Trusted Certificates database to sign client certificates, then all certificates you sign will automatically be trusted.
Obtain the Certificate Signing Request file (.csr). This can be done through e-mail or any other file delivery method.
Choose Tools > Certificate Signing Utility from the menu bar. The Sign Certificate Request dialog will appear.
Client certificate request - Click the folder to browse and select the Certificate Signing Request (.csr) file you want to sign.
Output client certificate - Browse and choose a folder in which to save the signed certificate (.crt) file.
Server certificate - Browse and choose the certificate you will sign with. This certificate must be in your trusted certificate database in order for clients submitting the signed certificate to connect to the site.
Server private key - Browse and select the private key file (.key) associated with the server certificate.
Enter the Passphrase associated with the server certificate.
Choose an Expiration date.
Click OK. The new certificate will be saved in the folder you selected.
