The following code replaces a password hash within configuration file - it replaces it with a newly generated hash.

Random hash is generated by the passgen() function.

This hash seems to be somehow wrong, it is different from the hash generated natively without using passgen()

problem:
print md5_hex(&passgen); != print md5_hex("same_string");

- System: Linux I would be really appreciate if anyone could suggest a working solution.


use strict;
use warnings;

use Tie::File;
use Digest::MD5 qw(md5_hex); 


my @array;
my $email='email@address.com'; 

tie @array, 'Tie::File', 'webpass.set' or die "$!";
  
foreach my $line (@array) {
  my ($user,$pass,$rest,$seed);
    
    if ($line=~/$email/ig){
   
    ($user,$pass,$rest)=split(/::{1,10}/,$line,3);
 
    $seed=passgen();
    
    #chomp $seed;
    
    $pass=md5_hex($seed);

   
    $line=$user."::".$pass."::".$rest;
   
    print $line;
    print "\nChanged \n";
 
    print "\n\nNew Password:",&passgen;
    
    exit 0;
    
    }

}
print "sry - your email has not been found!\n\n";


sub passgen {
   
   my ($random_string, $char, @chars, $ret );
    
   @chars=qw(a b c d e f);
    
    foreach (1..7) 
        {
        
        $random_string.= $chars[rand @chars]; 
    }
    
    
        return $random_string;
}
