possible to crack .7z file with sha-256?
#1
I am complete noob at this so please help. from google search, many results kept saying 7z/7zip uses sha-256.  then I came across this benchmark from github https://gist.github.com/epixoip/a83d38f4...804a270c40

it shows that 7z each 1080 GPU can only do about 7k to 8k hash/s (assuming password per seconds?), where as for sha-256 can go upwards of 3000 MH/s which is 3 billion hash/s compare to just 8k of 7zip. that is ~370000x faster.

is it possible to use hastcat with SHA256 for 7zip so its faster?

not -m 11600 (archive 7zip)
hashcat64.exe -m 11600 -a 3 hast.txt

instead use -m 1400
hashcat64.exe -m 1400 -a 3 hast.txt

edit: i just realize google is saying 7zip is using AES 256 and not SHA 256. what is the difference? also I can't seem to find AES 256 under help menu for -m in hastcat.

edit 2: google also says "To create that key 7-Zip uses derivation function based on SHA-256 hash algorithm. " so which is it, AES256 or SHA 256 i am so confused.
