How to use the jsencrypt function in jsencrypt

export default str => {
  let encrypt = new JSEncrypt()
  encrypt.setPublicKey(key)
  // console.log(str)
  return encrypt.encrypt(str)
}

Vue.prototype.$encruption = function (obj) {
  let encrypt = new JsEncrypt();
  encrypt.setPublicKey(
    `-----BEGIN PUBLIC KEY-----MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDyKmfJhgAHEK0Yo6qOtFB8sSfYIZBJUyyXi1X7EgkZo3kmMOu6/uT7SwC9EnqbiMySJfAlvB200ZMIk6e1NQrPLZpc5VSuzSQ3NqdXOdbNnhXAUeME8IcsbscK9XP8BxldMhUhIK+3zovI1VCY2kLO6TMwEVvTdH+F1jW/WFkplwIDAQAB-----END PUBLIC KEY-----`
  )
  return encrypt.encrypt(obj);
};

export const decryptAsymmetric = (privateKey, encryptedText) => {
  const crypt = new JSEncrypt();
  crypt.setPrivateKey(privateKey);
  return crypt.decrypt(encryptedText);
};

encrypt(publicKey, password) {
      var en = new JSEncrypt();
      en.setPublicKey(publicKey);
      return en.encrypt(password);
    },
    verify() {

export const encryptAsymmetric = (publicKey, actualText) => {
  const crypt = new JSEncrypt();
  crypt.setPublicKey(publicKey);
  return crypt.encrypt(actualText);
};

export const generateAsymmetricKeyPair = (keySize = 1024) => {
  const crypt = new JSEncrypt({ default_key_size: keySize });
  const keys = crypt.getKey();
  return {
    privateKey: keys.getPrivateKey(),
    publicKey: keys.getPublicKey()
  };
};
