WebDec 26, 2024 · A cryptographic hash function is a function that takes in input data and produces a statistically unique output, which is unique to that particular set of data. We would be using this property of Cryptographic hash functions to identify the contents of two files, and then would compare that to determine whether they are the same or not. WebThis is both because of the GPU type (CUDA or OpenCL) and because of varying memory sizes (some hash functions are more memory intensive than others). Ivan Golubev maintains a great table comparing the performance of pretty much every GPU on the market with a few hash functions (e.g. MD5, SHA1) though not bcrypt or scrypt.
