Stop letting AI pick your passwords. They follow predictable patterns instead of being truly random, making them easy for ...

Cryptographic hash functions are the foundation of modern blockchain systems and cybersecurity. They play a crucial role in ensuring data integrity, enabling digital signatures, and verifying ...

Engineer with 5+ years of experience at AWS. I write about various topics to rid myself of my imposter syndrome. Engineer with 5+ years of experience at AWS. I write about various topics to rid myself ...

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 ...

Let’s uncover how quantum resilience in Ethereum has already reached 20 percent and what this means for future blockchain security. Ethereum network security benefits from modular upgrades and long ...

Imagine this scenario. The year is 2030; deepfakes and artificial-intelligence-generated content are everywhere, and you are a member of a new profession—a reality notary. From your office, clients ...

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: This study presents a lightweight blockchain framework based on cryptographic hash functions that can run in resource-limited IIoT situations. Because traditional blockchain protocols ...

Microsoft is killing off an obsolete and vulnerable encryption cipher that Windows has supported by default for 26 years following more than a decade of devastating hacks that exploited it and ...

From the paper Fast Hashing of Variable-Length Text Strings (archived) by Peter K. Pearson with additional edits by jeblad (Dec 13, 2025). The core of the Pearson hash algorithm is fast execution on ...

A lightweight cryptographic hash function inspired by ChaCha20, designed for speed, simplicity, and efficiency in resource-constrained environments. Ideal for embedded systems, research, and ...
