WebSep 29, 2024 · A cryptographic hash function is a special class of hash function that has certain properties which make it suitable for use in cryptography. It is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (a hash function) which is designed to also be a one-way function, that is, a function which is infeasible ... WebSuccinctly, the generic cryptographic hash algorithms are designed to be fast. Protecting a password requires a slow cryptographic hash algorithm. A fast cryptographic hash algorithm, iterated 2^16 times, becomes a slow cryptographic hash algorithm.

WebSep 17, 2024 · The most used symmetric cryptography algorithm today is AES (Advanced Encryption Standard). AES is a cipher block system able to use 128, 192 and 256 key length where that key operates over blocks of 128 bits of plain text to generate 128 bits of encrypted text. AES is used pretty much everywhere. WebNov 17, 2011 · A Salt (random number) is used so that the same password does not always generate the same key. i.e. A salt is simply added to make a common password uncommon. A Salt is something we add to our hash to prevent rainbow attacks using rainbow tables which are basically just huge lookup tables that convert hashes to passwords as follows:
