## What it is
hash-wasm is a fast hash function library for browsers and Node.js implemented with hand-tuned WebAssembly binaries. It supports a wide range of algorithms including MD5, SHA-1/2/3, Keccak, BLAKE2/3, xxHash, CRC, and key derivation functions like Argon2, bcrypt, scrypt, and PBKDF2.

## Use cases
- compute md5 or sha256 checksums of files in the browser
- hash passwords with argon2 or bcrypt in nodejs
- calculate fast non-cryptographic hashes with xxhash for hash tables
- generate crc32 checksums for data integrity checks
- derive keys with pbkdf2 or scrypt in javascript
- compute blake3 hashes faster than pure js implementations
- hash data in web workers without native dependencies

## When to choose
- you need hash functions in both browser and Node.js with one library
- pure JavaScript hash implementations are too slow for your workload
- you need many hash algorithms behind a single consistent API
- you want small per-algorithm bundle sizes
- you need password hashing (argon2, bcrypt, scrypt) without native modules

## When to avoid
- you need hardware-accelerated hashing via native code (e.g. OpenSSL bindings)
- you only need one hash and a tiny native or built-in option exists (e.g. Node crypto)
- your environment cannot load WebAssembly
- you need streaming hashes over very large files with minimal memory in constrained environments
