I have a password file that has some binary data & user name and passwords are readable in a hex editor or with this code 

 
#!/usr/bin/perl -w
use strict; 
my $buff;
my $file ="/Perl/scripts/old/bak_PW/dkxy01_";
system("cls");
open (FH, $file ) or die "can't open $file: $!";
binmode(FH);
binmode(STDOUT); 
while (read(FH, $buff, 324)) {
    print STDOUT $buff;
}
close FH      or die "Closing: $!";

Below is output from a hex editor it seem like the data is in blocks of 324 bytes after the header, so from offset 0->23B is a header of sometype and the first record is from 23C->37F with user = MFG and password = MFG, next is from 380->4C3 user = ADRIANC and password = 08008 and it goes on from there.

my questions are how would one go about unpacking and repacking when one is unsure of what all the extra data means, is there an easy way of looking at this kind of a problem, I have read about intel,moto,big I and little I, but I am not sure if any of that applies here and if so how. My end goal is to make changes to the file and then upload it back to the tools so that all 65+ tools do not have to be manualy updated. Some of the records start with "RøzÄ" or "–úàê" and others ",RUâ". Also cx5000 seems to be an important stop or start point. Any ideas or links to indepth pack/unpack with detailed examples would be great if you are unable to id the system used to encode
