WebOct 14, 2024 · World population is about 7 billion. Someone with a database of all names and birthdays can brute force that in a few hours/days. Additionally, you can probably eliminate most of the people in that list, based on language proficiency, country of residence, etc and still have a reasonably good chance of undoing your hash. WebJan 5, 2024 · A hash function is an algorithm that transforms data of arbitrary size into a fixed size output. The output is a ciphered text called a hash value or a digest. The main objective of a cryptographic hash function is verifying data authenticity. Hash functions often are used in passwords.
