GM Global B Seed Security - Seed Key Calculator Tool 1.0

Would be interested in testing this tool on my personal truck. 2022.5 Silverado. MDI2/DPS already acquired. Hopefully this is last needed ingredient for solution.

hi, i need the password to open the zip file for the gb seed calculator

Hi, when I copied the seed into the calculator and press SEND the calculator disppear any idea how to solve this issue?

the calculator doesn't work don't waste your time

I have DPS read log, can you create key from data?

Yeah this thing's utterly useless the seed cannot be he cannot be calculated offline the way it has to be done is it has to communicate with their servers and get the key back from there it doesn't even get the key really the seed key only unlocks the security gateway the security gateway itself is what does the actual service 27 unlock it it doesn't completely different thing than any other one. Like a communicates with the server it grabs a token from there does the seed seed request to their servers the seed changes every time you requested when the key comes back down it gets past to the serial data gateway and then that gateway unlocks the module to flash I've done it before with a completely different server I just can't get a hold of that guy and I'm in desperate need of getting this thing programmed because I'm on like the serial data gateway and that's like programming that and doing the authentication handshake is literally the last step that stopping me from getting paid for this job I'm open to it so DM me or something if you have any way to get in there
