Decryptor supported options:

-w {wordlist} (omit -w to read from stdin)
-h {phantom_wallet_hash}
-o {output} (omit -o to write to stdout)
-t {cpu threads}
-s {print status every nth sec}

-version (version info)
-help (usage instructions)

./phantom_decryptor.bin -h {phantom_wallet_hash} -w {wordlist} -o {output} -t {cpu threads} -s {print status every nth sec}

./phantom_decryptor.bin -h phantom.txt -w wordlist.txt -o cracked.txt -t 16 -s 10

cat wordlist | ./phantom_decryptor.bin -h phantom.txt

./phantom_decryptor.bin -h phantom.txt -w wordlist.txt -o output.txt
