Implementation

Users

As of right now, individual users have no reason to use Ragnarok. Once can always ask a web administrator to incorporate Ragnarok into their web login system. This encryption algorithm is designed to make your data more secure without requiring you to do anything special.

Servers

Use a call to a perl script to encrypt a username and password. An example could be:

perl Ragnarok.pm --generate=upass --username='username' --password='password'

Note: It is IMPERATIVE to validate input before running this code.

If you just needed to return the username, you can run:

perl Ragnarok.pm --generate=upass --username='username' --password='password' --returnusername

Please see the [Back End Tutorial] for a tutorial on actual implementation.

Perl

Here is a sample of code that can be used as a model for the implementation (This comes from the POD).

    #!/usr/bin/perl
    use Ragnarok;

    my $r = new Ragnarok();

    # Always define the key before defining the code.
    # You can't type in the code on the keypad if you can't
    # get through the door :) Also, Ragnarok returns an error if you try.

    $r−>properties(ABOUTKEY, $aboutKey);
    $r−>properties(KEY, $r−>generate(ABOUTKEY));
    $r−>properties(ABOUTCODE, $aboutCode);
    $r−>properties(CODE, $r−>generate(ABOUTCODE));

    my $proof = $r−>generate(PROOF);
    $r−>properties(PROOF, $proof);

    if ($r−>properties(IRCODE, $installcode) == E_INVALID_IRCODE) {
       die "Sorry, invalid install code.";
    } else {
       # VALID INSTALL CODE
    }

    if ($r−>properties(IRCODE, $removalcode) == E_INVALID_IRCODE) {
       die "Sorry, invalid removal code.";
    } else {
       # VALID REMOVAL CODE
    }
