These scripts all deal with JavaScript Password Protection scripts. They are an elementary attempt to protect a site and should NOT be used to protect Top Secret information. They just keep the amateurs out. Pros can infiltrate such sites with these forms of protection. But, for free, they do a good job. They are very difficult to write - just look at the code.

Script Title: Cookie Protection
Details: 5.19 KB * Uploaded August 13 1997
Script Description:You can use a basic cookie script to keep visitors (that don't have the cookie on their system) from viewing certain parts of your site (kind of.... There are always ways around it). The cookie is placed when the password provided is correct. Then, when they are forwarded to the password protected page, the cookie allows them to stay. Those without the cookie are sent back.

Details: 2.97 KB * Uploaded August 13 1997

Script Title: Login Coder
Contributor: Dion
Contributor URL: http://www.iinet.net.au/~biab/
Details: 6.50 KB * Uploaded May 29 1998
Script Description: This is undoubtedly the best password protection JavaScript you'll ever find. Besides supporting multiple users, multiple passwords, and even multiple destination pages (after they successfully login), this script is presented in a very easy-to-use interface that you're sure to love! We *wish* we wrote this script, it's that good! (Note: Questions on this script should be directed to the author.)

Script Title: Multiple Users (Login Table)
Details: 1.60 KB * Uploaded May 15 1998
Script Description: Rather not have one password for access the Members-Only section of your site? Well, along comes this little JavaScript gem. You can set up a separate username and password for as many members as you want, and even give each a different page to go to after logging in!

Script Title: Multiple Users (Prompt)
Details: 1.29 KB * Uploaded May 15 1998
Script Description: This JavaScript is just like the previous Multiple Users one, but doesn't use a table interface to login. Instead, after clicking the Login! button, the script will ask them for their username and password, and then perform the password-protection. Very neat!

Script Title: Password Pro
Contributor: Lefteris Haritou (lef@writeme.com)
Contributor URL: http://www.geocities.com/~lef
Details: 2.55 KB * Uploaded October 26 1997
Script Description: This script uses a different approach to Password Protection. It still uses the password as the actual page, but it uses an encryption method that encrypts and checks the password. So if you fail to enter it correct after 3 times you go to a specific page (specified by the webmaster) and you don't get the annoying 404 page not found message as in other scripts. The password is password

Script Title: Password Prompt
Details: 0.58 KB * Uploaded August 13 1997
Script Description: If a visitor wants to go a password protected page, they must first enter the correct password on the page with this script. This script will just take you them to [password entered].html This is a very good script if JavaScript is enabled and as long as you have an index.html file in your directory. As an added bonus, it's only 8 lines! The password is the protected filename without the .html ending.

Script Title: Text Encryption
Contributor: Tomislav Sereg (tsereg@net.hr)
Contributor URL: http://www.inet.hr/~tsereg/jse
Details: 8.32 KB * Uploaded August 3 2000
Script Description: This JavaScript library provides encryption using simple, text-oriented method called column transposition. The idea is to write the plain text in block on the row-first bases. The text is then read column-first. The trick is in that the columns are not read from left to right, but in the order specified by the encryption key. Transliteration is also used.

Contributor: Francisco Ryan Tolmasky (iopossum@mailcity.com)
Contributor URL: http://iopossum.tripod.com
Details: 2.99 KB * Uploaded September 4 2000

Script Title: XOR Encryption
Contributor: Terry Yuen (kaiser40@yahoo.com)
Details: 3.97 KB * Uploaded August 11 2000
Script Description: Performs a bitwise XOR (Exclusive Or) on each byte of the data you wish to encrypt using the key you provide. Useful as an additional security precaution when sending sensitive information over the Internet. (However, this method is not foolproof and should not be your only form of security.) The author notes that longer and more random keys increase the strength of the encryption. Neat!
