Because SHA-1 is no longer considered cryptographically secure against determined attackers, it is possible to find collisions (two different inputs producing the same hash) or, for simple inputs, reverse it using .

In the context of torrenting or file sharing, this hash allows users to confirm they are downloading the exact file they intend to, rather than a malicious or corrupted alternative. This meant that a malicious actor could potentially
In 2017, Google and CWI Amsterdam announced the "SHAttered" attack, proving that two different PDF files could be crafted to produce the same SHA-1 hash. This meant that a malicious actor could potentially forge a digital document that possessed the same signature as a legitimate one. for simple inputs
