Cool Encrypter/Decrypter

[jeffsbaker]

I have created a web page that encrypts/decrypts messages using a key that the user provides. It is pretty simple. I mainly did it for entertainment value. It slowly encrypts/decrypts the message with a cool display.

I was wondering if this is the right place to discuss this with others. I want to make the encryption scheme a little harder to break. I think someone may be able to figure out how to decrypt a message without the key. If someone here could take a look at it and tell me how easy it is to do that, it would be great. I don't want to use any other algorithm out there. I just want to keep working on my own. I can make it better. I also am just using plain text characters because I want it to be able to be emailed easily.

Congrats on writing that yourself. You are on the right *****!

It was very easy to figure out the encryption splashed on the original text from the key though. It follows a very profound pattern.

Thank you guys for the feedback. I appreciate it. Yes, it is somewhat easy to figure it out. If someone uses a really short key, someone could probably figure out how to unscramble the message in a few hours or so through brute force. I think it would take a little while longer with a longer key though. However, I recently made a change, but put it under a different web page. The previous version only used the key to encrypt each letter by a difference of *0 characters. But the new one encrypts by a difference of 80 characters and is case sensitive. So it should be alot harder to crack.

Ok, I just put the new one up on the main site and it has a message with a link to the
old encrypter.

And, I thought about putting the encryption scheme in a PHP file, but I didn't want to take the time to write the code to pass variables between PHP and Javascript because I don't want it to switch pages. I also figured that, even though it is alot easier to figure out the encryption because the code is right there in the script, someone could still figure it out by typing a few words and then encrypting them and changing the key slightly each time.

Thanks again,
Jeff

thats cool dude! ! even though i had no idea what its used for it seemed very interesting

Nice work man, although you could secure things more by processing the encryption server-side with a language like PHP.
