Web19 mei 2016 · 1 Answer. As Richie Frame noted in the comments, you basically listed them in order of ascending collision resistance. The latter hashes have greater collision resistance due to their increased output size. With the exception of SHA-1 and MD5, this is denoted by the number in the name of the algorithm. For example, SHA-512 produces … Web24 dec. 2024 · MD5 suffers from a collision vulnerability,reducing it’s collision resistance from requiring 264 hash invocations, to now only218. 8 Attackers can take advantage of …

In particular, note that MD5 codes have a fixed length so the possible number of MD5 codes is limited. The number of strings (of any length), however, is definitely unlimited so it logically follows that there must be collisions.
