How to convert PFX file into a format Robo-FTP Server can use
PFX files, or Personal Information Exchange files, are a type of exported certificate file used in SSL. They are typically named with a .pfx or .p12 extension.
Robo-FTP Server version 3.2.5 and later ...
Robo-FTP Server version 3.2.5 and later is able to directly import certificates stored in PKCS #12 format with no conversion required.
If the PFX file contains both a public certificate and a matching private key you must put the file path only in the top Certificate File textbox and then leave the Private Key File textbox empty.
Robo-FTP Server version 3.2.4 and earlier ...
You can use OpenSSL to convert a PFX file that contains both a public certificate and a private key into a pair of .cer and .key files so they can be used by Robo-FTP Server.
You can download it from this web page: OpenSSL for Windows.
If you are running 32-bit Windows, then this specific download should work for you: OpenSSL Installer for 32-bit Windows.
Once you have downloaded the installer, launch it by double-clicking on it. Follow the instructions on-screen to complete the installation (accept all the default settings).
You can now convert the PFX file.
These instructions assume you have created a PFX file named Robo-FTP Server.pfx and copied it to the C:\OpenSSL\bin directory.
- Click Start | Run..., type
cmd.exeand click OK.
cd C:\OpenSSL\binand hit Enter.
openssl pkcs12 -in "Robo-FTP Server.pfx" -nokeys -out "Robo-FTP Server.cer"and hit Enter.
openssl pkcs12 -in "Robo-FTP Server.pfx" -nocerts -out "temp.key"and hit Enter.
openssl rsa -in temp.key -out "Robo-FTP Server.key"and hit Enter.
You should now be able to copy the resulting .cer and .key files to the C:\Program Files\Robo-FTP Server directory (or wherever you want to store them).
Browse to the .cer file from the Certificate Path Name field in the SSL Options tab of the FTP Server section of the Robo-FTP Server Console window.
