## What it is
Abracadabra is an open-source text encryption tool that transforms encrypted data into realistic Classical Chinese (wenyan) prose, using AES-256 plus compression and randomized sentence construction. It ships as a JavaScript/WASM library with a web app and browser extension, and can also decrypt the legacy 'Xiong Yue' cipher.

## Use cases
- encrypt text so it looks like classical Chinese prose
- hide encrypted messages in literary-looking text
- encrypt short strings with AES locally offline
- decrypt Xiong Yue (与熊论道) ciphertext
- compress text before encryption to shorten ciphertext
- embed a text encryption library in a web app

## When to choose
- you want ciphertext that blends in as normal Classical Chinese text
- you need local, offline AES-based text encryption in JavaScript
- you want tunable randomness and text style in encrypted output
- you need to decrypt legacy Xiong Yue encoded text

## When to avoid
- you need formally audited, standards-compliant cryptography for production security
- you need a permissive license for unrestricted commercial use (AIPL-1.1 has restrictions)
- you need encryption of non-text/binary data at scale
- you need output in languages other than Chinese

## Facets
- artifact type: library
- maturity: active
- function: cryptography, serialization, compression
- domain: security, privacy, developer-tools
- platform: browser, wasm
- tags: classical-chinese, text-encryption, steganography-like, aes, chinese-characters, browser-extension, natural-language-processing, javascript, web-server, nodejs
