Hello
Ive been doing some re-work on the way BlitzLockIT generates serial numbers.

Name: ????
Serial: 4248-AB-2719-8151-AA

anyone like to attempt to covert the serial number back to the registration name.

theres a example available here.

thanks to anyone that trys to break this.

that isn't really the way people usually break keygens, though, is it?

I mean, you often can't convert the numbers back into the names, for starters.

Is the Key PC dependant?


Kev(Posted 2003) [#4]
@Anthony. use any way possable. im wanting to see the strength of the encryption.

@darklordz. no its not PC dependant.

@Kev,
If the serial is not pc dependant all it would take is one malicious client to spread your serial....


Kev(Posted 2003) [#6]
yep there is that problem, although i will tackle the problem of making it PC dependant. one added benifit is that BlitzLockIT contains a database of hacked/spread serial numbers. so these can be checked against the user/serial that has been entered.

How will you update this database, client can shoose not to update the program


Kev(Posted 2003) [#8]
the serial database is intergrated into un-registerd compiled .exe, the database will be updated using BlitzLockIT Serial Administration Center. i now this does not offer a complete security solution. but it will offer some security.


maximo(Posted 2003) [#9]
do you mean that this exe will connect thru internet connection to the admin center and get the new data? That could work.

For a fair chance (and what crackers usually have access to) publish a few names and related serials followed by a name for which a serial needs to be generated by a keygen.


Kev(Posted 2003) [#11]
@gema yes.

@Imphenzia, the above download link is the serial generator. its up there for people to generate more than just the above user/serial.

No, usually they're just hashes...

Okay, I'll give it a shot. :o>


Kev(Posted 2003) [#13]
let me now how you get on FlameDuck.

If you reverse the 4th and 5th digit in a password you get the same serial. You could find your serial being rejected because of someone elses being passed around.

Example:

aaaba=1617-AA-3429-1333-DC
aaaab=1617-AA-3429-1333-DC

aaabaa=1614-AA-3833-1393-DI
aaaaba=1614-AA-3833-1393-DI


Kev(Posted 2003) [#15]
i was aware of this, and has now been fixed.

same reg names from above.

aaaba = 3240-EG-3016-0123-FA
aaaab = 3624-GD-2616-7843-CC

aaabaa = 3648-IE-3028-1804-EF
aaaaba = 4032-AB-2628-9524-IE

ive also done more work on the random serial generator
