I threw this together. It's not spectacular; it's just a simple custom tag
which uses ASCII codes for 0-9, a-z and A-Z. You'd call it like this:
<!--- example.cfm --->
<cf_password maxlength="8" returnval="newpwd">
<cfoutput>#newpwd#</cfoutput>
<!--- end example.cfm --->
It increases the likelihood of the use of numbers in a password; rather than
10 in 62, the likelihood is artificially increased to 1 in 3. I was too lazy
to do it right.
<!--- password.cfm --->
<cfparam name="Attributes.MinLength" default="8">
<cfparam name="Attributes.MaxLength" default="14">
<cfparam name="Attributes.ReturnVal" default="password">
<cfset intPwdLength = RandRange(Attributes.MinLength, Attributes.MaxLength)>
<cfset strPwd = "">
<cfloop index="i" from="1" to="#intPwdLength#">
<cfset WhichRange = RandRange(1, 3)>
<cfif WhichRange is 1>
<cfset Start = 48>
<cfset End = 57>
<cfelseif WhichRange is 2>
<cfset Start = 65>
<cfset End = 90>
<cfelse>
<cfset Start = 97>
<cfset End = 122>
</cfif>
<cfset strPwd = strPwd & Chr(RandRange(Start, End))>
</cfloop>
<cfset rs = SetVariable("Caller." & Attributes.ReturnVal, strPwd)>
<!--- end password.cfm --->
Enjoy!
