| Description: | http://www.users.dircon.co.uk/~crypto/ requires to work against a file in the format of /etc/passwd. Unfortunately on HPUX in trusted mode, the encrypted passwords for each user is stored in /tcb/files/auth/<first character of user name>/<user name> This little program goes through and creates a /tmp/passwords file with the encrypted password back in the second field. |

open (MERGED , "> /tmp/passwords");
open (PASSWD , "/etc/passwd");
while ( my $line = <PASSWD> ) {
my @fields = split(":", $line);
my $fletter = substr($fields[0],0,1);
my $trusted_file = "/tcb/files/auth/$fletter/$fields[0]";
if ( -r $trusted_file ) {
open (TRUSTED , $trusted_file);
while ( my $entry = <TRUSTED> ) {
next unless ( $entry =~ /u_pwd/ );

$fields[1] = $1;
