A more "secure" and user-friendly approach to this hack would be the following:

1. Requiring predefined questions which become part of the authentication procedure (entering in a username and seeing a question isn't a good idea from a security standpoint).

2. Converting the answer to lowercase before processing the md5 hash. ("What is my favorite flavor of ice cream?" A: "Strawberry" is not the same as "strawberry")

3. Creating an md5 hash of the secret answer prevents the administrator from making a visual determination to see if "Main Street" and "Main St." are actually both the correct answer. If the user cannot remember their password, chances are they won't recall the exact spelling and punctuation used in their answer.

Any thoughts?

Edit: These comments apply to Justin's version of the hack.

I'm assuming the easiest way to do this would be a strtolower() around any processing of secret_a and creating another table with the various questions and an id number (reducing the overall size of the database) (i.e. "What is the name of the town you were born in?" = "2")

secret_q would then have a value of "2"

I'll try doing this myself tomorrow, but I have a limited knowledge of the workings of vb
