Obviously if the hash is much smaller than the original file size, then you can't rule out the possibility of a collision. And if you look a the universe of all possible files of that size, there would have to be collisions simply because there are more possible files than hashes. However, for something like SHA256, it is unlikely that any two non-identical files created on this planet at any time in human history would have the same hash. Therefore, it is very likely (I mean like 99.99999999999999999999999999% or better) that provided an adequate algorithm is used, every non-identical file in the world will indeed have its own unique hash, just as stated. Theoretically it might not be guaranteed, but practically and statistically it is. However, I'll also say that I believe that the technology being used these days different than a straightforward hashing algo, in fact calling it a 'hash' is probably a deliberate deception to mask what they are really doing. And while I disapprove of the whole show, the possibility of hash collisions even on inferior algorithms or non-deterministic AI isn't one of my concerns. |

I don't know what exact technology is used and I'm not convinced if Halcyon knows it exactly either. I oppose this exact sentence quoted because it simply is not true. Even if you believe that a random collision is unlikely to ever occur in practice, deliberate collisions are also a possibility as soon as whichever algorithm they use is broken. |

But you can continue ignoring that part if you like. :popcorn: As I said, you can consider MD5 "broken", but it's still in wide use today, and that's perfectly OK for these types of applications. People much smarter than you have tried to argue this point in court and have failed. |
