## What it is
jsSHA is a pure TypeScript/JavaScript library implementing the complete SHA hash family (SHA-1, SHA-2, SHA-3, SHAKE, cSHAKE, KMAC) plus HMAC, with streaming update support. It runs in browsers, Node.js, and Deno with no native dependencies.

## Use cases
- compute sha-256 hash of a string in the browser
- generate HMAC signatures in JavaScript
- hash files incrementally with streaming updates
- calculate SHA3 or KMAC hashes in Node.js
- hash passwords or tokens client-side without native crypto
- use SHA hashing in Deno or TypeScript projects

## When to choose
- you need the full SHA family including SHA-3, SHAKE, cSHAKE, or KMAC in JavaScript
- you need a dependency-free, cross-browser and Node-compatible hashing library
- you need streaming/incremental hashing or HMAC support

## When to avoid
- you only need basic hashes and can rely on the built-in Web Crypto API or Node crypto module
- you need password hashing algorithms like bcrypt or Argon2
- you need high-performance native-speed hashing for large data volumes

## Facets
- artifact type: library
- maturity: stable
- function: cryptography, security, sdk
- domain: security, developer-tools, web-development
- platform: browser, cross-platform
