sjcl-ts

Stanford Javascript Crypto Library updated to ES6.

Tiny 2.72kB AES-GCM library

• Tiny: about 2.72kB after gzipped
• Mordern: pure ESM package
• Reliable: based on Stanford Javascript Crypto Library with minimal customization

Installation

pnpm add ts-sjcl

Usage

import sjcl from 'ts-sjcl'

const password = sjcl.codec.utf8String.toBits('PASSWORD')
const iv = sjcl.codec.utf8String.toBits('IV')

const cipher = new sjcl.cipher.aes(password)

export function encrypt(plaintext) {
  return sjcl.codec.base64.fromBits(
    sjcl.mode.gcm.encrypt(cipher, sjcl.codec.utf8String.toBits(plaintext), iv)
  )
}

export function decrypt(ciphertext) {
  return sjcl.codec.utf8String.fromBits(
    sjcl.mode.gcm.decrypt(cipher, sjcl.codec.base64.toBits(ciphertext), iv)
  )
}

console.log(encrypt('Hello World!'))
console.log(decrypt('0sFJ9r7c33z7gB4u1pD0xzuX48xaYVBGLj41UQ=='))
