md5 Question

mAGOO

Hi all,

I have just been fighting with md5 issue with both generating a key and comparing it with a user logon form. I finally got it working, but I do have a question about the actual generation of the md5 key.

I created a form with 2 fields one md5 password field and another simple text field with the value of the un md5 value.

eg md5 field would display "5f4dcc3b5aa765d61d8327deb882cf99" and straight text field would display "password'.

For some reason I could not get the correct value for the md5 field. The password and md5 would never match to the correct value.

Then I created a var for the password field and used the var in the update query and all worked fine.

Does anyone know why this would happen?

I always thought that md5 would would always pump out the same.

Cheers
Steph.

It will always pump out the same, so there must be something being added to the string, or something altering it. Is a newline or break token being added, or is the case of some or all of the characters the same, etc?

No it was outputting a completely diff string.

All I changed was basically this:

UPDATE blah, blah, blah, pwd = 'pwd', password = md5('pwd') blah, blah,

This gave me the odd output. Then I added a var and changed the query to include that var.

$pwd= 'pwd';

then query

UPDATE blah, blah, blah, SET pwd='$pwd', password=md5('$pwd') blah, blah,

and that worked.

As you can see, I was doing nothing extraordinary, I was just testing a couple of things before I made the changes to the live site.
