Hi guys, I had problems whit registration key (actkey) that sometime is the same for many users (this happen 2-3 times at year). Perhaps the key that is in my setup is only 16 char then can happen that 2 users have the same key. I solved the problem not making the key longer only but adding a timecode before the key (in this way is impossible to have 2 identical key) In the file inc_func_posting.asp add the line marked(line 69): ........... strKey = "" for j = 0 to 15 strKey = strKey & keyArray(key(j)) next 'timecode strKey=round(CDbl(Now())*10000)&strKey 'end timecode GetKey = strKey if action = "sendemail" then .......... in that way the code is a sum of a number that change every 10sec plus the actkey calculated as before.
I don't know if the new version of the forum have an algoritm more efficient, I hope that can be helpfull for someone.
You could use a simple date/time extraction like this:
strKey = DatetoStr(strForumTimeAdjust) + strKey
That'll get you a leading string of the year/month/day/HH/MM/SS (followed by the initial key) - totaling 46 characters. Then, the odds against a duplicate registration key issued at the exact same second would be astronomical.
Yes..I saw that is possible to use till 32 chars, and is quite difficult but still is possible to have the same key..for that reason I used this algorithm. Also whit this solution you can make shorter the key ( 5-6 chars plus the timecode(10 chars)=16 chars). I think whit this solution you can have less char and real less probability to have the same key.
