And here's another one that I prepared earlier:
<cfscript>
function getRandChar() {
// Set the lower & upper ASCII limits
low = 48;
high = 122;
randCharAsc = randrange(low,high);
// constrain to alphanumerics by excluding certain ranges
if ((randCharAsc gte 58 and randCharAsc lte 64) or (randCharAsc gte 91 and
randCharAsc lte 96))
// Hey look kids, recursion
randChar = getRandChar();
else
randChar = Chr(randCharAsc);
return randChar;
}
function randPassword( length ) {
pwd = "";
for(i=1;i lte length;i=i+1) {
pwd = pwd & getRandChar();
}
return pwd;
}
</cfscript>
<cfoutput>#randPassword(6)#</cfoutput>
