Installation

$ npm install --save @cichol/cryptography

Usage

// For using default preset.
import { generateKeys, encrypt, decrypt } from '@cichol/cryptography/default'

// For using lightweight preset.
import { generateKeys, encrypt, decrypt } from '@cichol/cryptography/lightweight'

// For using post quantum preset.
import { generateKeys, encrypt, decrypt } from '@cichol/cryptography/post-quantum'

const [ publicKey, privateKey ] = await generateKeys()

const encryptedData = await encrypt('Hello, world!', publicKey)

await decrypt(encryptedData, privateKey) // 'Hello, world!'
