Testing the utility i get the following traceback and error:

echo '{"A": 1234}' | python3 hc1_sign.py | python3 hc1_verify.py

Traceback (most recent call last):
File "hc1_sign.py", line 149, in
out = b'HC1:' + b45encode(out).encode('ascii')
AttributeError: 'bytes' object has no attribute 'encode'
Traceback (most recent call last):

if (cin[0] == 0x78):

I got the same problem

Try just
out = b'HC1:' + b45encode(out)

Same problem here. Is there any solution for this error?

out = b'HC1:' + b45encode(out) -> doesn't work for me.

I have another problem with:

Traceback (most recent call last):
File "/Downloads/ehn-sign-verify-python-trivial/hc1_sign.py", line 149, in
out = b'HC1:' + b45encode(out).encode('ascii')
AttributeError: 'bytes' object has no attribute 'encode'

Remove encode

Remove encode

@senzacionale
Thank you for answering but, where should I remove encode? I don't understand your answer.
