I have question about how to generate different keys like

12345-67890 is key and second key is 09876-54321 and many others

So how to do in asm.. Can some tell me this!

Use a PRNG to obtain random values for parts of the key that dosent matter.

I don't want to generate random numbers, i want it like generating different keys saved in it. And if i am wrong please you u can just mention an example below

So you're asking how to write a keygen?

Same answer as always - lena's tuts, specifically number 36. I think you have a lot of reading to do yet though!

No bro, i don't want to write to a keygen or need need any source code, i just wan't to generate keys, the pseudo code for only generating part. and i am through with lena#36 tutorial

The problem is like if i press generate button i can generate one key and if i press again the the generate button it should out put the next key i want, you can say it even as keymaker!

Geez ure one hard headed individual. Like I said above use a PRNG to get random values for parts of the algo that does not have to be a specific value. Some algos you can do this and some you can not.

Extremely simple example.....

INCLUDE MASM32.INC
INCLUDELIB MASM32.LIB
INCLUDE \MASM32\MACROS\MACROS.ASM 
.code
SeedPRNG PROC
	INVOKE GetTickCount
	INVOKE nseed,EAX
	RET
SeedPRNG ENDPKeygen PROC hWnd:DWORD
Local SerialBuffer[255]:BYTE
Local dwSerial1:DWORD
Local dwSerial2:DWORD
	INVOKE RtlZeroMemory,ADDR SerialBuffer,SIZEOF SerialBuffer
	INVOKE nrandom,-1
	MOV dwSerial1,EAX
	MOV dwSerial2,EAX
	XOR dwSerial2,12345678h
	XOR dwSerial1,12345h
	INVOKE wsprintf,ADDR SerialBuffer,SADD("%.8X-%.8X"),dwSerial1,dwSerial2
	INVOKE SetDlgItemText,hWnd,IDC_SERIAL,addr SerialBuffer
	RET
Keygen ENDP

That what i wanted thanks mate
