Cryptographically hashed
WebConsider that a cryptographic hash algorithm excels at producing different digest values for even the slightest differences in inputs. Even a 1 bit change in the input causes a cascade of changes yielding a completely different hash value. Pre-image resistance is a necessary characteristic for a cryptographic hash algorithm. Now look at ... WebDec 10, 2015 · A cryptographic hash function is an algorithm that takes an arbitrary amount of data input—a credential—and produces a fixed-size output of enciphered text called a hash value, or just “hash.” That enciphered text can then be stored instead of the password itself, and later used to verify the user.

WebJun 22, 2024 · Overview. Hashing is a cryptography method that converts any form of data to a unique text string. Any piece of data can be hashed, regardless of its size or type. In traditional hashing, irrespective of the scale, type, or length of the data, the hash produced by any data is always the same length.
