EME

EME (Encrypt-Mix-Encrypt) wide-block encryption in TypeScript/JavaScript.

Intro

Pure and full TypeScript/JavaScript port of .

Almost line-to-line "translation", with all the ported test cases.

Usage

``bash
npm install @fyears/eme
`

`typescript
import { EMECipher, AESCipherBlock } from "@fyears/eme"
import { deepStrictEqual } from "assert"
import { webcrypto } from "crypto"

(async function(){
const key = new Uint8Array([
0,1,2,3,4,5,6,7,
8,9,10,11,12,13,14,15
]) // 16-byte Uint8Array the user provided for the AES part

const tweak = new Uint8Array(16)
webcrypto.getRandomValues(tweak) // iv

const input = new Uint8Array(64) // some Uint8Array the user provided
webcrypto.getRandomValues(input)

const bc = new AESCipherBlock(key)
const eme = new EMECipher(bc)

const output = await eme.encrypt(tweak, input)
const inputBack = await eme.decrypt(tweak, output)

deepStrictEqual(inputBack, input)
})()
