I wrote 2 scripts;

This script WORKS GREAT via command line; %perl -Tw pipetogpg.cgi 

# START PIPETOGPG.CGI
$ENV{"PATH"} = "";
system('echo "this is a longer test message" | /usr/local/bin/gpg -ear
+ docwebb > ./Temp/encrypted_file.gpg');
exit;
# EOF

This script does NOT WORK (supposed to work via web browser) but it writes an empty file;

#!/usr/bin/perl -Tw
use strict;
use CGI::Carp qw/fatalsToBrowser/;
 
&encrypt_data;
print "Content-type: text/html\n\n";
print "done<BR>";
exit;
 
sub encrypt_data
 {
   my $old_path = $ENV{"PATH"};
   # CLEAR ENV{"PATH"} SO PERL DOESN'T COMPLAIN ABOUT TAINTED DATA
   $ENV{"PATH"}="";
 
   # PATH CLEARED ABOVE SO WE NEED A FULL PATH IN THE COMMAND LINE
   system('echo "this is a longer test message" | /usr/local/bin/gpg -
+ear testkey > ./Temp/encrypted_file.asc');
   
   # RESTORE PATH
   $ENV{"PATH"} = $old_path;
 }
#EOF

I do NOT understand why almost identical code produces an empty file

Thanks
