You mean AES 128 key??
If you are, I heard that reading does not require the aes key from nxp.
Or you just mean sector keys for crypto1?.
I don't know any sector keys of the card .
Is it possible to get keys of mifare plus by mfoc&mfcuk?
Yes, I mean the 128bit AES sector key. In SL3 Crypto1 is no longer used.
If you don't know the sector key you cannot perform any operation. This is the intention of a key and NXP learned their lessons.
We confirmed that we read the amount information with some apps and the nxp tag info app. (Of course, it is the app of the company that issued the card and another company.) I do not think the company would have used the keys nxp has.
If you can not read without key, can you analyze frequency through hackrfone or get key through proxmark3 snoop?
I think my knowledge can be short. Could you tell me how to do more analysis?

You can always read the uid and ATS, but without the keys you cannot get any further on a mf plus in sl3 mode.
