In this tutorial, we build an elastic vector database simulator that mirrors how modern RAG systems shard embeddings across distributed storage nodes. We implement consistent hashing with virtual ...
Security firm Mandiant has released a database that allows any administrative password protected by Microsoft’s NTLM.v1 hash algorithm to be hacked in an attempt to nudge users who continue using the ...
Abstract: The secure hash algorithm (SHA) is a widely used function for password hashing. This study introduced a modified SHA-512 algorithm by modifying the message scheduling, hash construction, and ...
Abstract: The growing number of data breaches has brought attention to how important it is for web apps to use secure password hashing procedures. The drawbacks of conventional hashing algorithms, ...
Streaming giant Plex is urging its customers to change their passwords after it disclosed a data breach of one of its user databases. The company said in a post on Monday that it was aware of a ...
As security professionals, it's easy to get caught up in a race to counter the latest advanced adversary techniques. Yet the most impactful attacks often aren't from cutting-edge exploits, but from ...
A lightweight Flask web app with secure user authentication — including registration, login/logout, and protected routes. Built with Flask-Login and SQLAlchemy, this project demonstrates best ...
