Full noop, key with Crapto, MFOC says no sector with key

Here is my full snoop.

I have run several snoops through crapto and have come up with the same key multiple times. When I enter the key into MFOC it is telling me no sectors are encrypted with the key.  There are several lines from the snoop past the tag response and perhaps I should be doing something with them, not sure. 

52
TAG 04 00
    93 20
TAG 19 fd 1a a5 5b
    93 70 19 fd 1a a5 5b e2 0b
TAG 08 b6 dd
    60 05 58 2c
TAG 90 a6 d2 ce
    13 07 d3 b5 b5 0e 54 fa
TAG 7e 72 97 1f
    71 41 7d 8b
TAG 23 a8 41 45 33 2a 02 0b e5 e5 99 4e 19 14 24 58 b3 61
    50 00 57 cd

TEST2
$ ./test2
nt': f1359c5f
nt'': 74610c96
ks2: 443bc8a5
ks3: 0a139b89
Found Key: [e5 23 c1 1d b3 0b]

Any help is appreciated.  Thanks.

Never mind.  For what ever reason I was generating the wrong key.  I recompiled and was able to generate a correct key.  MFOC is now finding the remaining.

On the original snoop is there any information there that tells what is being read or where it is being read from?

Re: Full noop, key with Crapto, MFOC says no sector with key

the part   [60 05 58 2c ],   tells you that the reader is trying to Authenticate , using keyA, sector 5

If you read up on the command set for Mifare classic, you will understand better whats going on.
