Elliptic curve cryptography library (NodeJS, Browser and Pure JS)
This library is a port from eccrypto it makes use of native libraries on NodeJS and Browser enviroments with pure javascript fallbacks.

const encrypted = await eccryptoJS.encrypt(keyPairB.publicKey, msg);
const decrypted = await eccryptoJS.decrypt(keyPairB.privateKey, encrypted);
// decrypted.toString() === str
This library is intended for use in a Browser or NodeJS environment, however it is possible to use in a React-Native environment if NodeJS modules are polyfilled with react-native-crypto
