fmogavero,

For the pgp, try looking at the several pgp modules. For the other system call, you could do something like this:

<bold>note: untested code</bold>

$/ = undef;
open( FILE, "somescript.pl" ) || die "can't open: $!"
$script = <FILE>
close( FILE );

$ARGV[0] = "Whatever $DECRYPT_WORK_PATH$PLAINTEXT_FILENAME IS";
eval $script;
if( $@ ) {
  print STDERR "Error: yada yada\n";
}

or maybe even simpler

$ARGV[0] = "whatever";
do 'somescript.pl'
[download]
