## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 1672, "days_push": 650, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
An interactive web application that visually explains how the SHA-256 hash algorithm works step by step, hosted at sha256algorithm.com. Built with React (create-react-app), it is aimed at students learning about hash functions and cryptography.

## Use cases
- learn how sha256 hashing works step by step
- visualize the sha256 algorithm internals
- teach students about cryptographic hash functions
- understand message padding and compression in sha256
- demo tool for explaining hashing in a cryptography course

## When to choose
- you want an interactive visual walkthrough of the SHA-256 algorithm
- you are a student or educator teaching hash function internals
- you want to fork or extend an educational cryptography visualization

## When to avoid
- you need a production SHA-256 hashing library for your application
- you need well-tested, maintainable cryptographic code
- you need hashes other than SHA-256 or general crypto primitives

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: cryptography, security, developer-tools
- domain: security, education, web-development
- platform: browser
- tags: sha256, hash-functions, visualization, interactive-tutorial, cryptography-education, algorithms, web-server, nodejs
