WebHashing and encryption both provide ways to keep sensitive data safe. However, in almost all circumstances, passwords should be hashed, NOT encrypted. Hashing is a one-way function (i.e., it is impossible to "decrypt" a hash and obtain the original plaintext value). Hashing is appropriate for password validation.

WebMar 31, 2024 · “Hashing” refers to the process of using an algorithm to transform data of any size into a unique fixed-sized output (e.g., combination of numbers and letters). To put it in layman’s terms, some piece of information (e.g., a name) is run through an equation that creates a unique string of characters. Hashing is a computationally and storage space-efficient form of data access that avoids the non-constant access time of ordered and unordered lists and structured trees, and the often exponential storage requirements of direct access of state spaces of large or variable-length keys.
