Comment (by pmetzger):

 Replying to [comment:6 ryandesign]:
 > We use two algorithms so that a compromise of one algorithm does not
 compromise the integrity of the files.

 I think the probability of a high quality exploit that occurs without
 prior warning against any of the modern hash algorithms is quite low. That
 said, SHA-3 or BLAKE2/BLAKE3 are good options as I said.

 We should also systematically get rid of reliance on MD5 (people with
 inexpensive machines can fake that at this point) and SHA1 (people with
 expensive machines can fake that at this point.)
