[Feature] Speed up checksum comparison with newer hashing methods

Post by dreamflasher »

Thank you for your great software!
I would appreciate a lot if you would add blake3 or better XXH3 (Czkawka has those), as those would bring a 10x speed improvement: https://jolynch.github.io/posts/use_fas ... lgorithms/

XXH3 is the fastest: http://cyan4973.github.io/xxHash/

Just to align expectations: Just because your hash is 10x faster it does not mean that the comparison is faster. You cannot get comparison time lower than disk read time.
