btcrecover extract scripts
So btcrecover extract scrips creates a base64 hash of wallet.dat files something looking like this 

Bitcoin Core encrypted master key, salt, iter_count, and crc in base64:

then can be used in btcrecover --data-extract So the question is Can hashcat use this type of hash? Link to extract scrips U know works in hashcat my question is the Extractor script is that a faster algorithm and if so can it be implemented in hashcat.
Only the base64 encoded hash of -m 18800 = Blockchain, My Wallet, Second Password (SHA256) for hashes is supported with latest (beta) version of hashcat (

see for an example hash

other hashes can be converted by from johntheripper (magnumripper branch)
