Ascii
Encryption |
(Internet Explorer Only) A very simple encryption method that uses random
values for each character. Interestingly, you can encrypt the same string as many times as
you want and the result will always be different. Best used with short strings. |
Character
Encoder |
Encrypts a string by converting each character to it's ASCII key code.
Supports two-way encryption - from a string to the numeric code, or from the numeric code
back to the string. You can, for example, send the encrypted code to a friend and have
them decode it with this script. |
Login Coder |
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! |
Multiple
Users |
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! |
Multiple
Users Prompt |
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. |
Password
Generator |
Generate a random password with the ability to include special characters
and password restrictions. |
Text
Encryption |
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. |
Three Tries |
If you want to "protect" a site and don't have CGI access, you
can try this JavaScript. Visitors get three tries to enter the correct password then they
are refused entry. Note: The password is: password |
Virgenere
Encryption |
A fine example of the classic virgenere script and is nearly impossible
to decode, even when using frequency analysis. This script is also entertaining since you
can actually see the encryption taking place. |
Xor
Encryption |
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. |
