hashing

In the digital realm, securing passwords is paramount. One of the common methods for securing passwords is through hashing. In this article, we will explore how to securely hash passwords using sha256sum along with a salt in Linux Bash. A: Hashing is the process of converting an input (like a password) into a fixed-size string of bytes, typically a hash, which appears to be random. It's necessary because it secures passwords in a way that even if someone accesses the hashed version, they cannot easily deduce the original password. Q2: What is sha256sum? A: sha256sum is a Linux command-line utility that computes and checks SHA256 (256-bit) cryptographic hash values.
