Sample Python Script to understand the encoding, decoding, storage and sharing of keys

from umbral import PublicKey, SecretKey
import base64

alices_secret_key = SecretKey.random()
alices_public_key = alices_secret_key.public_key()

serialized_public_key = base64.b64encode(bytes(alices_public_key)).decode('utf-8')
# Now, serialized_public_key has type string. It is stored in the database, as well as used to
# transfer the keys over the network

# Upon receiving the serialized_public_key string over the network, or after reading it from
# the database, we can re-construct the Public Key object using the code below
new_public_key_bytes = base64.b64decode(serialized_pub_key.encode('utf-8'))
new_public_key = PublicKey._from_exact_bytes(data=new_public_key_bytes)
