Tom said:
I need a javascript that will accept the username "frederic" and the
password "ozanam" on my page "member,html" that will allow those who
input this data to access my page "member2.html". [...]
This is really an insecure way to go. How secure do you actually need
this page to be?
Contradictory to common belief, javascript passwords can be secure; it
all depends on the underlying algorithm. The OP's major problem is that
he can't safely crypt the redirect to member2.html, since that is
something the javascript itself needs to decrypt somehow.
A safe javascript password script:

/***************************************************************
* *
* JAVACRYPT: CLIENT-SIDE crypt(3) USING JAVASCRIPT *
* *
***************************************************************
* *
* This Javascript allows you to calculate the encrypted *
* password generated by the UNIX function crypt(3) on your *
* computer without using an online script in PHP, PERL, *
* shell, or any other server-side script. The only changes *
* you need make in this are in function dP(), which is right *
* below the end of this comment. Refer to the directions *
* there for details. *
* *
* I wish I could take full credit for this script, but there *
* are several people who deserve most of the credit *
* *
* First and foremost, I thank John F. Dumas for writing *
* jcrypt.java, a Java-based implementation of crypt(3) and *
* from which this Javascript is heavily based (actually, I *
* just did a direct port from his code, using Sun's tutorial *
* and my knowledge of Javascript). I additionally thank *
* Eric Young for writing the C code off which Dumas based *
* his script. Finally, thanks goes to the original writers *
* of crypt(3), whoever they are. *
* *
* If you have questions, I suggest you ask John Dumas about *
* them, as I have no real idea what any of this code does. *
* Base the questions off his source code, as Javascript and *
* Java are (in basic operators) nearly identical. *
* *
* jcrypt.java source code can be found at: *
