## What it is
A Node.js utility library providing hashing functions (md5, sha1, sha256, hmac), base64 encoding/decoding, and HTML/URL escaping helpers. It supports strings, Buffers, and deterministic hashing of objects with sorted keys.

## Use cases
- compute md5 or sha1 hashes of strings and buffers in node
- generate deterministic hashes of javascript objects
- base64 encode and decode strings including urlsafe variants
- escape and unescape html entities
- generate hmac signatures
- hash strings in hex or base64 output

## When to choose
- you need a small, well-tested set of hashing and encoding helpers in a Node.js project
- you want deterministic object hashing with sorted keys
- you prefer a single dependency over pulling in larger crypto utility suites

## When to avoid
- you only need Node's built-in crypto module and want zero dependencies
- you need cryptographic-strength password hashing (use bcrypt or argon2 instead)
- you are not working in a JavaScript/Node.js environment

## Facets
- artifact type: library
- maturity: stable
- function: cryptography, serialization, developer-tools
- domain: developer-tools, backend, web-development
- platform: cross-platform
- tags: hashing, md5, sha1, sha256, base64, html-escape, npm-package, typescript, nodejs
