I am with Tom on that one... Better to make something that works 100%
than to double-check the output.
However, if you want to double-check the output, I would say keep it
simple. Check each rule individually:
must be exactly 8 characters in length
must have at least 1 number
must have at least 1 uppercase letter
must have at least 1 lower case letter
<cfset strPassword = "Ben4Prez" />
<cfif (
REFind( "^.{8}$", strPassword ) AND
REFind( "\d+?", strPassword ) AND
REFind( "[a-z]+?", strPassword ) AND
REFind( "[A-Z]+?", strPassword )
)>
<!--- GOOD. --->
<cfelse>
<!--- BAD. --->
</cfif>

Why not just write a better generator ?
1 Create a random number between 0 and 9
2 Create 1 random upper case letter
3 Create 7 random lower case letters
Concatenate all the results.
There is a built in function to do 1. Once you've done that, you can
generate random numbers with in a range, so you can do 2 (via the ASCII
code for the letters). Once 2 is done, you can use it to do 3 by calling
it 7 times and just ucase() the result.
