SHA256 algorithm can be still used for making sure you acquired the same data as the original one.
HASH CALCULATOR GPU VERGE PASSWORD
Some years ago you would protect your passwords from hackers by storing SHA256 encrypted password in the your data base. So it is no longer recommended to use it for password protection or other similar use cases. With the newest hardware (CPU and GPU) improvements it is become possible to decrypt SHA256 algorithm back. This makes it suitable for checking integrity of your data, challenge hash authentication, anti-tamper, digital signatures, blockchain. SHA256 algorithm generates an almost-unique, fixed size 256-bit (32-byte) hash. Even if only one symbol is changed the algorithm will produce different hash value. If you would like to compare two sets of raw data (source of the file, text or similar) it is always better to hash it and compare SHA256 values. A cryptographic hash is like a signature for a data set.

Obviously, we do not understand how is this even allowed and how proud are all those companies mentioned on the storefront supporting crypto mining business.

A retailer called “Nyugen Cong PC” is seemingly unbothered about this fact and is now offering systems with eight RTX A4000 cards strictly for cryptominers. It looks like content creators and professionals thinking of buying one of the RTX A4000 GPUs with GA104 GPU might need to reconsider their plans as well. This is mainly because local retailers and Internet Cafés have turned their business into either cryptomining operations. Gamers in Vietnam have been struggling to find graphics cards at good price for their rigs for 2 years now. Even workstation graphics cards are a subject to crypto abuse
