32 Simple and very unsafe example login page for CGIscriptor.pl. The password is first hashed with the
33 site specific salt (as it is used to store the password on-site). Then it is hashed with a random,
34 one-time salt. Effectively, creating a one-time password. Only the last value is send to the server.
35 The server has both salt values stored. It will ignore anything except the username, hashed password, and
39 The Session Ticket information is stored in
<a href=
"http://www.xul.fr/en/html5/sessionstorage.php">
40 <em>sessionStorage
</em></a> with key
<em>CGIscriptorPRIVATE
</em>. Older browsers might not implement
41 <a href=
"http://www.xul.fr/en/html5/sessionstorage.php"><em>sessionStorage
</em></a>, or it might be
42 turned off in the

60 There are three default test accounts, all three have password
<em>testing
</em>:
62 <li>test: A SESSION ticket account
</li>
63 <li>testip: An IPADDRESS ticket account
</li>
64 <li>testchallenge: A CHALLENGE ticket account
</li>
69 The Salt and Ticket values are all created using SHA256 on
64 Byte of output from
<em>/dev/urandom
</em> in HEX.
