About Collision
Verifying that a file you downloaded or received is actually the one you were
expecting is often overlooked or too time-consuming to do. At the same time, it
has become very easy to get your hands on a file that has been tampered with, due
to the mass increase of malicious webpages and other actors.
This tool aims to solve that. Collision comes with a simple & clean UI, allowing
anyone, from any age and experience group, to generate, compare and verify MD5,
SHA-256, SHA-512, SHA-1, Blake3, CRC32 and Adler32 hashes.
