Javascript Password ProtectionBy: Timur Abdrakhmanov - http://timurkz.buildtolearn.netArticle Word Count: 542 words [Comments (0)] Total Views: 115 Views |

The protection of web pages using a password |
When you click "Login", a yellow box appears where you can enter
the username and password. If the password and login are
correct, then after clicking Enter you will be redirected to
page members.php . All of this is stored in an external file
config.js . The content of config.js in my case is:
The username and password can be either dude1/pass1 or
dude2/pass2 .If you want to add more accounts, just copy and
modify the if statement. In each case, you will be redirected to
page members.php, and you can also change it easily in the code.
This was all i was going to cover. However, i have one more
extremely important notice: Don't use it to protect important
information! All of the above can be bypassed VERY easily by
almost everyone, and you should use it if you don't need any
super-secure protection. KZ Server

Now let's look at the code. When you enter the correct
password, a box appears saying that Access is Granted, and the
rest of the page is loaded. If the password is incorrect, you
are redirected to denied.php. I used a little trick with the
password here that can stop some unexperienced hackers ;)) the
FAKEPASS is not the actual password, even though you can make it
look like it. This is just a variable that is described in an
external file - "prompt.gif". This is another trick - the
external Javascript file has an extension .gif , which is used
for images. The file however contains text, and the server will
correctly treat it like a text file, not an image. So the
content of prompt.gif is:
readonly="readonly"> var FAKEPASS = "the_real_password";
As you see, here our variable is substituted with the word
"the_real_password", which is the actual password.
The second option in protecting a page with Javascript is much
prettier, and it actually allows you to have several login and
password accounts. The code is:
cols="65" readonly="readonly">
When you click "Login", a yellow box appears where you can enter
the username and password. If the password and login are
correct, then after clicking Enter you will be redirected to
page members.php . All of this is stored in an external file
config.js . The content of config.js in my case is:
The username and password can be either dude1/pass1 or
dude2/pass2 .If you want to add more accounts, just copy and
modify the if statement. In each case, you will be redirected to
page members.php, and you can also change it easily in the code.
