[Armory] Does lmdb file contains the private key? Reading complete LMDB file

[Armory][1] creates `Wallet file` and `lmdb` file when a new wallet is created. I did a super deep disk clean to see if I could recover the wallet file but I was unable to find it. Only file I was able to find that is `armory_*****_wallet.lmdb` mainly around 102KiB. I am not sure does it contains anything related to the `Wallet file` but I am just trying to read what's in it.

I have created a wallet from scratch and share my results with it, example [lmdb file][2] that is created by the `Armory`.

I have followed [guide-1][3], [guide-2][4], and [guide-3][5] to be able to read the file.

My script:

```
#!/usr/bin/env python3

import lmdb
import caffe

lmdb_file = "armory_2tG9psLQX_wallet.lmdb"
lmdb_env = lmdb.open(lmdb_file, subdir=False)
lmdb_txn = lmdb_env.begin()
lmdb_cursor = lmdb_txn.cursor()
datum = caffe.proto.caffe_pb2.Datum()

for key, value in lmdb_cursor:
   print(key)
   print(value)

print("\n--------------\n")
for key, value in lmdb_cursor:
   print(key.decode('utf-8'))
   print(value.decode('utf-8'))
```

---------

This only prints out:

```
b'99AxiN7y'
b'\x00\x00\x00\x00\x00\x00\x02\x00\x01\x00\x00\x00\x00\x00\x00\x00\x04\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00k\x00\x00\x00\x00\x00\x00\x00\n\x00\x00\x00\x00\x00\x00\x00'
b'WalletHeader'
b'\x00\x00\x00\x00\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x03\x00\x00\x00\x00\x00\x00\x00\x06\x00\x00\x00\x00\x00\x00\x00'

--------------

99AxiN7y
k

WalletHeader

```

Since the file size is much larger I am not sure why does it able to print only a single character as a value. Is there any other way to read the `lmdb` file in depth or its size does not matter? Seems like `99AxiN7y` is the wallet-id of the original wallet file.

I am sure the file is not corrupted where I have tried with a new `armory_***wallet.lmdb` file that is created by the `Armory` and similiar result is generated.

=> The real question is if the lmdb file contains the private keys too and can we recover our wallet from it?
