Simple Encryption

A lot of people ask about encryption, well I found a great tutorial that explains a great encryption method. From what I have researched this encryption is XOR256.

While this says Password Encryption, the routine can be used to encrypt just about any text from URLs to cookies!

Encrypting Passwords with ASP

Update:

This method does have some quirks for example it can sometimes, depending on the output of an encrypted text, throw SQL query errors.

To solve this simple encode them using hex or base64.
I prefer using hex as it is less trouble some to decode. Here is a code sample that will show you how to do this:

String to ASCII Codes/ASCII Codes to String

Ah, the good old encrypt_text function.
I abandoned this encryption function long time ago in favor of the MD5 encryption scheme used here
The Encrypt_Text has dissapointed me in the past due to the selection process by which users select their passwords. Some password combinations don't fare well with this function.
On the other hand, the MD5 function has not dissapointed me ever since I incorporated it into my login scripts, you can even use it in conjunction with URLs to keep spiders out of your site on secured portions of it.
Anyways, just my two cents after having used this function. With some dissapointment

nice code to know about indeed - moved this to the Code Help forum which would hold useful code samples from now on.
we can also point on this thread when someone ask for encryption help.

Just found this thread while looking for a way to sanitise form data.

Would ASCII encoding form input prevent sql injection or can hex values also cause sql query errors? I thought that hex values could be used to inject sql or is this just via the querystring?

this is not relevant for sql injection attack. ascii/hex code are still only characters - the database does not care what characters you try to insert. only problem is with the single quote that must be replaced as it's the text delimeter.
