Web app and framework offering modular conversion, encoding and encryption. Translations are done client side without any server interaction — cryptii.com

Several quick start options are available:

• Use the latest live version or download the latest release.
• Clone the repo: git clone [email protected]:cryptii/cryptii.git
• Install the node version specified in .nvmrc.
• Run npm install to install the dependencies.
• Run npm run-script build to build into the dist/ folder.
• Run npm run-script test to test the source code.
• Run npm run-script watch to watch for changes.

This framework and web app tries to reflect a wide variety of ciphers, formats, algorithms and methods (called 'bricks') while keeping them easily combinable. There are two categories of bricks: encoders and viewers.

Encoders manipulate content by encoding or decoding it in a specific way and using specific settings.

Example usage:

const bricks = cryptii.BrickFactory.getInstance()
const encoder = bricks.create('rot13')
encoder.setSettingValue('variant', 'rot47')
const result = encoder.encode('Hello World') // returns a Chain object
result.getString() // returns 'w6==@ (@C=5'

Viewers allow users to view and edit content in a specific way or format.

Chain objects encapsulate the actual content used and returned by encoders and viewers. This content can either be a string, an array of Unicode code points or a Uint8Array of bytes.

Chains are immutable. You define its content by passing one of these representations as first argument to the constructor.

const a = new cryptii.Chain('🦊🚀')
const b = new cryptii.Chain([129418, 128640])
const c = new cryptii.Chain(new Uint8Array([240, 159, 166, 138, 240, 159, 154, 128]))
cryptii.Chain.isEqual(a, b, c) // returns true

The object handles the translation between these representations lazily for you. You can access any of these through getter and additional convenience methods.

const string = chain.getString()
const codePoints = chain.getCodePoints()
const bytes = chain.getBytes()
