Project: A Secure Encrypted Password Vault

This ten-part series builds a complete, production-grade secure password vault in Rust, teaching you cryptographic principles, secure memory handling, and real-world threat modeling. Over 10 articles, you'll implement a CLI tool that stores secrets encrypted with AEAD, derives keys using Argon2 password hashing, masks sensitive input, and withstands attack scenarios.

By the end, you'll have a working encrypted vault, understand why each security choice matters, and know how to audit password managers for vulnerabilities. Whether you're building internal credential storage, a personal vault, or hardening an application's secret management, this series gives you battle-tested Rust patterns and the confidence to deploy encryption safely.

The series progresses from cryptographic fundamentals (what is Argon2? why AEAD?) through implementation (CLI setup, secure input, file formats) to advanced topics (memory zeroization, security testing, threat modeling). Each article includes runnable code examples from a real Rust project, not toy snippets.
