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 … Web25 jan. 2024 · The MD5 hash algorithm is a widely used method for creating a unique fixed-length “digest” or “hash” of a piece of data, such as a file or a password. The algorithm takes in any type of data as input and outputs a 128-bit hash value, which can be represented as a 32-character hexadecimal string.

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. Share exteris bayer
