refer to this post for working tutorial: https://ragnarok-online-2.com/forum/new-4-28-08-account-creation-t2510 This formula is PUBLIC DOMAIN: http://en.wikipedia.org/wiki/Luhn_algorithm It has many examples on the website and is most notebly explained with the following: "The algorithm is in the public domain and is in wide use today. It is not intended to be a cryptographically secure hash function; it was designed to protect against accidental errors, not malicious attacks. Most credit cards and many government identification numbers use the algorithm as a simple method of distinguishing valid numbers from collections of random digits." - wikipedia MATH FORMULA: YYMMDD-SXXXXXC YY = two digit year MM = two digit month DD = two digit day - S = sex [1 = male, 2 = female] X = random seed X = random seed X = random seed X = random seed X = random seed C = CHECKSUM generated by luhn ((11-(((Y1*2)+(Y2*3)+(M1*4)+(M2*5)+(D1*6)+(D2*7)+(S1*8)+(X1*9)+(X2*2)+(X3*3)+(X4*4)+(X5*5))%11))%10) % = modulus steps, multiply each number in the order 1,2,3,4,5,6,7,8,9,1,2,3,4 modulus 11 11-number above number above modulus 10 to get C OR YOU COULD REPLACE THE LETTERS WITH WHATEVER YOU WANT AND COPY AND PASTE IT INTO GOOGLE TO GET THE CHECKSUM SO ITS A VALID KSSN. EXAMPLE: http://www.google.ca/search?q=%28%2811-%28%28%2881*2%29%2B%2862*3%29%2B%280*4%29%2B%282*5%29%2B%282*6%29%2B%282*7%29%2B%281*8%29%2B%285*9%29%2B%284*2%29%2B%283*3%29%2B%282*4%29%2B%281*5%29%29%2511%29%29%2510%29 YYMMDD-SXXXXXC Thanks for visiting my math lesson. This post is in response to the garbage DMCA notices i've been seeing lately over at http://www.chillingeffects.org/notice.cgi?sID=1845 [Korean Information Security Agency requests removal of ID numbers from Google] FIX YOUR SYSTEM. THIS WAS NOT MEANT TO BE USED AS A CRYPTOGRAPHICALLY SECURE HASH FUNCTION (see wikipedia) |

| Kornflake Posts count: 4 | Problem is when you register you're supposed to copy paste something from your guide on the ornge button thing. But IE doesnt allow copy paste on that page and the whole thing doesnt work on Firefox. And some people report you need Korean IP for it. |

yeah, you can use the shift+insert keys on your keyboard to paste into boxes. I'm updating my script to allowed ctrl-c ctrl-v |
