I'm using Crypt::GPG in a script that takes text and files submitted via a web form and generates an encrypted email. If I run the script in a shell, the following statement works and returns encrypted data. But when called as a CGI, it returns 'undef'. 
$gpg->encrypt("Some plain text", $recipientID);

I've set the path to the gpg binary, and specified all the options required to ensure the encryption requires no user input (--always-trust --no-permission-warning --home /path/to/keys) and verified this in a shell.

I've tried setting some environment variables (TERM=dumb, SHELL=/bin/sh and LANG=C) early on in my script on the recommendation of a colleague, but it made no difference.

The script has been in active use for a couple of years on a now obsolete RedHat distro, and is being migrated to a current machine so the modules have all seen some updates. I'd rather not make any big changes to my script that are going to require changes at the recipient.

In reply to Module works when run in a shell, but not when run as a CGI by azureblue
