Here's the function I use:
<cffunction name="generateShortCode" access="public" output="false"
returntype="string">
<!--- Create a 6 digit, base 32 code that will be used to identify
this particular user--->
<cfscript>
var numberToUse = RandRange(1,1000000000,"SHA1PRNG");
var shortcode = FormatBaseN(numberToUse,32);
</cfscript>
<cfscript>
while(Len(shortcode) LT 6){
shortcode = '0'&shortcode;
}
</cfscript>
<cfreturn shortcode />
</cffunction>
Obviously that generates a 6 character string, not a 4 character
string, but change the 6 to a 4 and Bob's your Uncle.
