p2p - How could a file be corrupted? -

-

my understanding hash list in info should protect integrity of downloaded files, files corrupted? taken torrent poisoning

a malicious user pollutes file converting format indistinguishable uncorrupted files (e.g. may have similar or same metadata).

how file polluted , still pass integrity test?

thanks

i making assumption here, think confusing terms "data" , "metadata". if file corrupted, data mess, information system uses identify file intact according system. example, present glass full of clear liquid , tell it's water. glance can see entirely possible water, , drink find out vodka. system, , when "used" glass of liquid found out contents not expected.

now give glass expert on verifying glasses of clear liquid filled water, , you, "no, not meant be". "expert" checksum comparison tool. checksum generated entire file, not metadata.
