How to use gpu on bruteforcing SHA256(MD5('password'))

[Vido]

see the output of --help

sha256(md5(pass)) is not currently supported

-a 3 needs a mask and you specify a mask directly after the hash file

e.g.

Code:

./hashcat64.bin -a 3 -m 4700 -D 1,2 -o cracked.txt --increment --increment-min 2 hash.txt ?d?d?d?d?d?d?d?d?d?d

I don't know why you use this "bf-cs-buf", it was never an option available for the modern hashcat binary (again see --help).


Where is the hashing algorithm sha256(md5(pass)) used ? is this a common software/cms etc ?

Ok great tnx for explanation.Sha256(md5(pass)) Its used on huawei router backup confing file,

Edit:
How can I pipe md5 output from one hashcut to another which will do sha256 ?
