Problem
You have a program on your Windows web server that can only be run from command prompt but is needed in your ColdFusion web application.
Solution
You can use the ColdFusion function cfexecute to run the program.
Detailed explanation
Example of using cfexecute with GNUPG on Windows:
NOTE: double quotes used to pass spaces in paths, key, and user names but passphrase with GPG can not be passed with quotes if not contained in passphrase
<cfexecute name="C:\WINDOWS\system32\cmd.exe" arguments="/c ""C:\inetpub\utils\gpg1.bat"",passphrase,""publickeytouse"",""C:\fullpath\somefile""" variable="result" timeout="2">
</cfexecute>
<cfoutput>#result#</cfoutput>
Windows .bat file gpg1.bat
@ECHO OFF
REM This batch file creates a ASCI PGP signed file encypted using 3DES
REM %1 = Senders'
passphrase for private key to encrypt file
REM %2 = User Key of sender to sign and encrypt file
REM %3 = Public Key of recipient to sign file
REM %4 = File to encrypt and sign - include fullpath and extension
ECHO %1|gpg --homedir "C:\full_path_to_stored_keys\gnupg" -a --passphrase-fd 0 --cipher-algo 3des -sce --yes -u %2 -r %3 %4
