[sha256] Hash inside a hash

[eachzin]

Hello dear hashcat community, im pretty new to hashing stuff, and even mask generating but, can you guys help me with something?


i know for sure that a sha256 im trying to break is indeed another sha256, so for sure a 64character between 0,9 and a to f.. so i was trying to generate it with maskprocessor but that will take how much of space? haha like 1tera?

is there any way of doing this better? any possible way to make at least "faster" or is this the only way?

any help is appreciated just a small light will also be greatfull 


Thanks in advance, eachzin
