OK, I have been banging my head over the last little while trying to get GPG working through PERL and finally came across this gem of a tutorial. Thank you!

My only issue is that I still cannot get it to work. In an attempt to emulate the tutorial on my machine, I created two scripts trialencode and trialdecode, listed here

#################
## trialencode ##
#################

use strict;
use GPG;

my $gpg = new GPG(homedir => '/home/jaf/.gnupg');

my $plain="ARGHH!!";

my $phrase=$gpg->encrypt($plain,"jaf0faj\@xxxxxxx");
die $gpg->error() if $gpg->error();

print "Plain: $plain\n\nEncoded:\n$phrase\n";
open (OUT, ">trialencoded");
print OUT $phrase;
close (OUT);

#################
## trialdecode ##
#################

use strict;
use GPG;

my $gpg = new GPG(homedir => '/home/jaf/.gnupg');

open (IN, "trialencoded");
my $phrase=join("",<IN>);
close(IN);

my $message=$gpg->decrypt('HtfdIggtw?',$phrase);

print "\n==========================\n\nEncoded:\n$phrase\n\nDecoded: [
+$message]\n";
print "\n\n\$gpg->error message: ".$gpg->error() if $gpg->error();

When I run them consecutively via "perl trialencode && perl trialdecode" encoding works fine, but decoding fails. Here is the output from this:

Plain: ARGHH!!

What am I doing wrong? BTW, if I perform a "gpg --decrypt trialencoded on the command line, where trialencoded is the dump of the encoded phase generated in trialencode, gpg successfully decodes the text, as shown below (using HtfdIggtw? as the passphrase for the secret key)!

gpg --decrypt trialencoded

You need a passphrase to unlock the secret key for

ARGHH!!
