Hashing is a cybersecurity technique that converts data into a fixed-length string of characters using a mathematical algorithm.
Hashing in cybersecurity works by transforming data into fixed-length outputs called hashes. These hashes serve as unique identifiers for the data. The process involves passing data through a hashing algorithm, which then uses a hash function to map the data into a seemingly random string of ch...
