Brute forcing sha256 possible?

Hi, I would like to discuss whether in theory it is possible to brute force sha256 hash.

2^255

 

Depending on what kind of equipment you have, what the length is, and what charset is useable, it could take a VERY long time.

 

 

Here is a calculator you can use to run various scenarios and find out the time it would take.

you'd be lucky if you crack it before there is no more universe

Impossible to crack, but can crack the patterns that output from it, still quite 0.0001℅ chance

What do you mean by "the patterns that output from it"? Can you give an example?

You have to know what does the input looks like before you can construct your desired table or your locksmith stuff even you know the hash...
