## What it is
Cryptii is a web app and framework for modular conversion, encoding, and encryption, performed entirely in the browser with no server interaction. It composes 'Bricks' (encoders and viewers) into sequential 'Pipes' that support a wide range of ciphers, formats, and algorithms like Base32, Morse code, and the Enigma machine.

## Use cases
- convert text to base64 or base32 in the browser
- decode a morse code message online
- encrypt text with the enigma machine
- convert hex to ascii85
- encode text with a1z26 or bacon cipher
- chain multiple encoding and cipher steps together
- decode data offline without uploading it to a server

## When to choose
- you need quick client-side encoding, decoding, or classical cipher conversion without sending data anywhere
- you want to chain multiple conversion steps visually and edit content interactively
- you need a self-hostable or offline-capable encoding playground

## When to avoid
- you need strong modern cryptography for securing real data — this is a conversion/education tool, not a security product
- you need bulk or scripted batch conversions from the command line
- you need server-side or API-based encoding at scale

## Facets
- artifact type: application
- maturity: active
- function: cryptography, serialization, web-framework, developer-tools

- platform: browser
- tags: encoding, ciphers, enigma-machine, client-side, base64, modular-conversion, bricks, web-server, nodejs
