hi all

i send my fiorst crackme to here, i just want to know how to crack some registation number protection like this. actually, i donot know how to crack it due to acknowledged difficulty of cryptography.

this crackme is not very hard to track, i didnot put any anti-debug code inside, if u can find a vaild [user name] and [registration number] then u will obtain a right message.

i will improve it for researching more strong registration number protection technique. if u enjoy it, pls email me to disscuess any thing in metamorphism or polymorphism technique within registration number protection. tks for ur time.
