If only we had checksums or file hash integrity.

Will they add checksums to verify the checksums?

Surely this isn't a problem with checksums/hashes to verify the integrity of the files?

Doesn't a checksum verify that the file you have is the same one the distributor intends you to have?

They have checksum hashes but not crypto verifiable signatures.

Were the posted checksums also replaced?

Foxboron Jun 4, 2014 View on HN

Couldnt this be countered by writing your own script checking the hash of the files X times a day?

jrsims Jul 27, 2008 View on HN

But they're adding checksums right? Anyone see any holes in that?

If the binary you're downloading might have been modified, how do you know that the hash you're checking against hasn't been as well?

You're right, I confused checksum with hash.
