Python based VAPID key-pair generator

vapid_helper.py

import base64
import ecdsa

def generate_vapid_keypair():
  """
  Generate a new set of encoded key-pair for VAPID
  """
  pk = ecdsa.SigningKey.generate(curve=ecdsa.NIST256p)
  vk = pk.get_verifying_key()

  return {
    'private_key': base64.urlsafe_b64encode(pk.to_string()).strip("="),
    'public_key': base64.urlsafe_b64encode("\x04" + vk.to_string()).strip("=")
  }

Thanks for this code snippet. It worked like a charm.
