You can also try using my Python 2 script for dumping the wallet (it's loosely based on pywallet, and might work better with some corrupted wallets)

Code:

import sys
import struct
from bsddb.db import *
from hashlib import sha256

# Dumps the private keys from a wallet.dat file.
# Inspired by pywallet.

B58 = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz"

if not len(sys.argv) == 2:
   print("Usage: %s <wallet_file>" % sys.argv[2])
   sys.exit(1)

def read_size(buffer, offset):
   size = ord(buffer[offset])
   offset += 1

   if size == 0xfd:
   size = struct.unpack_from("<H", buffer, offset)[0]
   offset += 2
   if size == 0xfe:
   size = struct.unpack_from("<I", buffer, offset)[0]
   offset += 4
   if size == 0xff:
   size = struct.unpack_from("<Q", buffer, offset)[0]
   offset += 8

   return offset, size

def read_string(buffer, offset):
   offset, string_len = read_size(buffer, offset)
   return offset + string_len, buffer[offset: offset + string_len]

def b58_encode(d):
   out = ""
   p = 0
   x = 0

   while ord(d[0]) == 0:
   out += "1"
   d = d[1:]

   for i, v in enumerate(d[::-1]):
   x += ord(v)*(256**i)

   while x > 58**(p+1):
   p += 1

   while p >= 0:
   a, x = divmod(x, 58**p)
   out += B58[a]
   p -= 1

   return out

def b58check_encode(d):
   checksum = sha256(sha256(d).digest()).digest()[:4]
   return b58_encode(d + checksum)

db = DB()
db.open(sys.argv[1], "main", DB_BTREE, DB_RDONLY)

items = db.items()

for item in items:
   k, v = item
   koff, voff = 0, 0
   koff, item_type = read_string(k, koff)

   if item_type == "key":
   koff, pubkey = read_string(k, koff)
   voff, privkey = read_string(v, voff)

   if len(privkey) == 279:
   secret = privkey[9:9+32]
   else:
   secret = privkey[8:8+32]

   if pubkey[0] != "\x04":
   secret += "\x01"

   print(b58check_encode("\x80" + secret))
   print(secret.encode("hex"))
db.close()

Thanks for your script; it is working for uncrypted wallet.dat file. Could you please advice how to recover encrypted wallet.dat file.
