# AnyHash

> A private, zero-latency, 100% client-side hash generator suite built with Astro, Tailwind CSS v4, and the Web Crypto API.

AnyHash computes MD5, SHA-256, BLAKE3, bcrypt, and Argon2id hashes entirely in the visitor's browser, and compares MD5, SHA-1, SHA-256, SHA-512, and BLAKE3 digests side-by-side. Inputs are never uploaded: there are no servers, no accounts, and no analytics. Each tool page also explains the algorithm in depth (how it works, its security properties, and when to use it).

## Tools

- [MD5 Hash Generator](https://anyhash.online/md5): QA/fingerprint hashing for checksums and file verification. MD5 is broken for security purposes — the page explains why and recommends SHA-256.
- [SHA-256 Hash Generator](https://anyhash.online/sha256): Fast, secure integrity hashing via the browser's native Web Crypto API (SHA-256, with SHA-1/SHA-384/SHA-512 support).
- [BLAKE3 Hash Generator](https://anyhash.online/blake3): The fastest modern hash, computed in-browser via WebAssembly — roughly 20x SHA-256 throughput, with text, hex, base64, and file input.
- [bcrypt Hash & Verify](https://anyhash.online/bcrypt): Salted password hashing with selectable cost factor (4–16), including a live verify mode.
- [Argon2id Hash & Verify](https://anyhash.online/argon2id): The current recommended password KDF, computed in a Web Worker with selectable memory/iterations/parallelism and a verify mode.
- [Compare Hashes](https://anyhash.online/compare): Side-by-side MD5, SHA-1, SHA-256, SHA-512, and BLAKE3 digests for one input string — a one-shot hash comparison matrix with an in-depth guide to choosing an algorithm.
