WebNov 26, 2024 · Hashing is a cryptographic process to encrypt data using a mathematical function that is uniform, consistent, and one-way. The process involves encoding any given text or data into a cipher value, which is a fixed-length key to represent the original string of data. The most popular usage of the hashing algorithm is the implementation of the ... WebFeb 25, 2024 · Recap. A cryptographic salt is made up of random bits added to each password instance before its hashing. Salts create unique passwords even in the instance of two users choosing the same passwords. Salts help us mitigate hash table attacks by forcing attackers to re-compute them using the salts for each user.

WebOct 2, 2024 · A hash function can never be reversible because it is not lossless (perhaps with the exception of extremely short plain texts). That's why hash collisions are possible: two hashes may represent more than one plain text.
