which hash function out of md5, sha1, crc 32 is the best in terms of minimum collisions?

Question

i am interested in uniquely identifying files using hash functions and i would like to use that hash function which produces hashes that have minimum collisions and thus are most reliable in terms of uniquely identifying very large number of files

Answer 1

SHA1 collision rate is roughly 2^80, CRC64 is roughly 2^63 (not sure about CRC32), and MD5 is 2^64.

Answer 2

As Lyra mentioned, sure we do, LOL! I even have felt some thing draw closer over an prolonged volume of time now. Now I even have started to experience an urgency, a could be nonetheless, Be alert, Be watchful. I not basically see differences, types, & complicated strains converge with out, yet I experience differences interior of additionally which at the instant are not genuinely shared. Many reward!

Answer 3

SHA1 creates a longer key. Therefore, it's less likely to generate the same key.
