use python 2.7 to run the extractor.we have some sample wallets in sample_wallets folder.the name of the wallet is also password of the wallets.
C:\Tools\core-decrypt-master\core-decrypt-master>python walletinfo.py sample_wallets/1234.dat
the tool requires 3 arguments-OpenCL device to use(Intel iGPU,AMD,Nvidia cards),encrypted hash,dictionary.we will use sample wordlist from the same repository.
C:\Tools\core-decrypt-master\core-decrypt-master>core-decrypt.exe --device 1 c0f3f5d18948424baf25613f91d8953c7347f5cf5d2b523550f02748d9f97ed1414609b1ce5abb850002fcb5 word_lists/0000_to_9999.txt
now we will test another sample wallet whose password is combination of city+numerical digit+city.it will be required to use 3 different dictionaries for possible password matches.
C:\Tools\core-decrypt-master\core-decrypt-master>python walletinfo.py sample_wallets/london2tokyo.dat
next we will pass this encrypted masterkey to the tool
C:\Tools\core-decrypt-master\core-decrypt-master>core-decrypt.exe --device 1 07c98426f3c0fc5226941894f229e2af98f8820c68e229c268926632111ba1fb414609b1ce5abb850002f489 word_lists/cities.txt word_lists/0_to_9.txt word_lists/cities.txt
within seconds the tool hit the passphrase of the wallet.we used three dictionaries here.cities.txt+0_to_9.txt+cities.txt.the tool made total of 2500000 combinations from all three wordlists to find the possible match.this is important if you remember part of the passphrase and willing to narrow down the search criteria.
