A recent Irregular study reveals that AI models such as Claude Opus 4.6, OpenAI GPT‑5.2, and Google Gemini 3 Flash produce passwords with striking patterns, making over half of generated passwords predictable, which poses serious security risks despite appearing strong.
This article presents seven practical Bash shell scripts for Linux system administration, covering automatic file backup, disk usage alerts, old log cleanup, server reachability checks, DNS resolution monitoring, HTTP service health checks, and random password generation, each with explanations and code examples.
This guide shows how to create random passwords using pwgen, generate an RSA key with OpenSSL, then encrypt and decrypt those passwords via command‑line tools, including example commands and sample outputs, while emphasizing security best practices for key handling.
This article explains the fundamental differences between Linux's /dev/random and /dev/urandom, why high‑quality randomness is critical for security, how each device generates numbers, and provides practical commands for creating strong passwords with urandom.
This tutorial explains how to create complex, high‑entropy passwords on Linux using GPG or OpenSSL, optionally filter out special characters with sed, and then assess password strength with the cracklib‑check tool on CentOS 8, illustrating both weak and strong examples.
This article presents three Python approaches for generating random strings, including single captcha-like codes, password lists, and batch generation functions, demonstrating the use of the random and string modules to create alphanumeric sequences.
Learn how to create high‑entropy, hard‑to‑guess passwords on Linux using three command‑line tools—pwgen, OpenSSL, and GPG—covering installation, usage options, batch generation scripts, and additional utilities for secure credential management.
This article shares practical techniques for generating passwords that are easy to remember but difficult for others to guess, including using initials of poems, personal info combined with app names and random numbers, and custom keyboard patterns, while emphasizing the importance of a consistent rule.
