import stringphone

#

Generate the pre-shared topic key.

key = stringphone.generate_topic_key()

#

Instantiate three participants, each with a copy of the key. In practice, these will be distinct devices.

t1 = stringphone.Topic(topic_key=key)
t2 = stringphone.Topic(topic_key=key)
t3 = stringphone.Topic(topic_key=key)

#

Encode a message to the topic.

encoded1 = t1.encode(b"Hey guys! This is t1!")

#

Both other participants can read the message.

print(t2.decode(encoded1, naive=True))
print(t3.decode(encoded1, naive=True))

#

Reply to t1 with another message.

encoded2 = t2.encode(b"Hi t1! This is t2, I got your message.")

#

Similarly, this message will also be readable by both other participants.

print(t1.decode(encoded2, naive=True))
print(t3.decode(encoded2, naive=True))
