Is it possible to crack a password hashed with sha256 with hashcat? [with screenshots]

SHA256 algorithm was invented to generate 256-bit (or 32-byte) hash. They write it will take you several years to crack it. It's true, but there're cases you can brute-force it (for example, with hashcat tool). At least you can try. In this article I'm using openSUSE Linux distro and openCL framework drivers for my NVIDIA GeForce GTX 1060 Mobile graphic card.

How to verify the checksum of a downloaded file in Solus OS Linux

Why do you need checksum?

Checksum serves to verify, that there was no corruption while downloading a file and that original file is the same as you have on your hard disk after downloading.

First of all you have to get correct checksum of the downloaded file from owner of the file or website, where you got that file. Normally you will see something like this:

SHA-256 checksum: c66aa2a0d49d5eced6f95dcb2f029907791e7b26c3381747318cce0007fbc198

md5: c3b3d4bc455ee51147e41c8f6b2d5c2a
