Error - doesn't look like the right key #31

Closed eyJhb closed 5 years ago

I'm trying to recover the keys for a NFC tag, and have found the B key for all blocks of the device (works fine with mfoc, does not complain etc.), but as soon as I insert them into libnfc_crypto1_crack, as

libnfc_crypto1_crack <key> 60 B 60 A

I get the following error

Reader-answer transfer error, exiting.. <key> doesn't look like the right key B for block 60 (sector 15)

And as stated, mfoc reads using the B key without complaining at all!

Any ideas or suggestions?

This looks like a new issue. I'll take a look as soon as I can.

Hey I should probably have read your report more carefully last time. I thought you had redacted the argument you passed.

You obviously need to replace <key> with a known key for this sector.

@dioxygene something I did wrong, cannot remember what. Closing as this is not a issue.
