Topic: Davinci Jr and Mini NFC Password requests.
There are a number of people who can now generate the password required for the NFC cards used in the Jr and Mini.
We have a hardware solution - not a way to decrypt anything.
To keep the other threads "clean", can you please request the password in this thread.
When we supply the passwords we do ask for the PACK code in return. (if you don't return the PACK, don't expect a second card password )
All we need to start is the card UID - or the first 2 pages of data from the card (as it's in there)
The UIDs, Passwords and returned PACK codes will all be made public - so anyone can join in and try and crack the algorithm...
that's the goal ..
If you think you can help us and work out the algorithm, please look at the attached csv file.
Of general interest, I have added some card no's at the end starting with 0x0000000, then 0x0000001 and then bit-shifted until 0x8000000
Identical passwords occur in some of the bit-shifted passwords, this may help!
I think the encryption algorithm is AES as the chips on the main board have this functionality... anyone good at cracking AES?
For those who have a restrictive firmware in their Mini (all fw versions) or Jr (post 2.2.0) and want to be able to re-create tags at with different UIDs their own leisure - instead of swapping. Follow this instructable.
