A Perl script doesn't properly work
 
I've a problem with a Perl script, it gives me an incorrect output. If I run it with:
Code:

perl perlscript.pl hirszdesign@gmail.com A4F2-C6BB-1F44
it prints:
Code:

Usage : perlscript.pl e-mail key-id
 e-mail : your e-mail
 key-id : a string in hex that has a XXXX-XXXX-XXXX format
 output:  9E-8D-D5-37-6C-89

I know it's incorrect, because if I ran it in my old SuSE 9.1 (I've FC4 now) the output was other.

Can someone run it with the same data that I and post me the results?

The link for it is:
hirszdesign(DOT)tripod(DOT)com(SLASH)perlscript(DOT)pl
(I can't post attachments and URLs... :( )

We'll need to have a copy of perlscript.pl if you want us to run it.

Edit: just noticed your well hidden link to the script, but can't download it.:(

Can you post the content, within [ code ] tags?

Code:

#!/usr/bin/perl
use Digest::MD5  qw(md5_hex);
printf "Usage : perlscript.pl e-mail key-id\ne-mail : your e-mail\nkey-id : a string in hex that has a XXXX-XXXX-XXXX format\n";

this code has been obfuscated.
You'll need to download a new version or something.

Hirszu 11-29-2005 01:02 AM

OK, and if I downloaded it with aMule? There was only one file of this sort... :confused:

How to fix it manually?
