| Aug 7, 2019 at 6:21 | comment | added | Patriot | @forest I know, but I found it interesting nevertheless. I see that you are right about implementations. I was thinking about quantum mechanics, but that is FAR over my head. | |
| Aug 7, 2019 at 5:42 | comment | added | forest | It's absolutely impossible for an identical pair of messages to not have an identical hash. There is no such scenario that would make that possible for an (unkeyed) hash to spit out different outputs for the same input. Now, an implementation might screw something up in edge cases, and the stray gamma photon might flip a bit or two in memory, but those are all incorrect evaluations of a hash (i.e. not the hash). | |

| Aug 6, 2019 at 6:07 | comment | added | SEJPM | A is literally impossible because hash functions are deterministic (unless you're talking about MACs but this doesn't seem to be the case here). | |
| Aug 5, 2019 at 20:15 | comment | added | Maeher | Those are some very weird options. | |
