Then you understand how statistically impossible it is to craft a modified distro that passes a CRC check?
And by statistically impossible, I mean this in a thermodynamic sense, as in that it is much more likely that you are a brain floating in a void that cohered completely from nothingness due to vacuum energy than it is that any given iteration of a modified file of considerable length will match the same CRC as an established, published, vetted copy.
It is about 100 times easier to randomly guess the private key of a bitcoin wallet than it is to iterate arbitrary changes to match CRC results.
There is a reason it is still the gold standard of file authenticity despite it being literally based on a largely unchanged 50 year old technology.
