What is the cryptographic algo used here?

Could you please tell the cryptographic algo used in this 9 digits serial number: WGr160093579 on Microsoft-IIS/8.0?

What exactly are you trying to achieve?

implement the same algorithm for my project @cpradio

To do what? Are you simply trying to validate Serial Numbers? Or generate Serial Numbers when someone purchases a product? It really doesn’t seem that difficult to do.

I’m not so sure that “WGr160093579” is a hash.

I see some that are 8, 16, 32, 40, 48, 56, 64, 80, 96, and 128 characters long.
But I don’t see nor know of any that are 9 digits long (or 12 characters if you count the “WGr” as part of it)

As this is a “serial number” what makes you think a crypto algo was used to create it?
My guess is it’s simply some kind of auto-incrementing id value.

Generate @cpradio

While you are right (as the next would be WGr160093580 in that order) what trick would be used to generate the corresponding pins (as pins would be generated at random)
If cryptography is now the issue here, what’s the algo, otherwise what trick?

SERIAL: WGR160093579 SERIAL:WGR160093580
PIN:123407689545 PIN:385906271492

PIN (Personal Identification Number), kind of like a password.

It doesn’t look like a hash to me. 12 digits only with no “A-F” i.e. decimal not hex.

Randomization could be easily done, the resource hit would be ensuring uniqueness.
