[g1im2]

i am sorry, the information less, i use ubuntu 18.04 and running adb with 1.0.41 vesion. clone this project and use setup.py to install. if i use sign_pycryptodome type to connect device, it can't auth and always throw the exception with DeviceAuthError if i run program. and i try working with sign_cryptography type to hope it can solve authError, but this error was happened, i don't know how to fix or skip it.

Did you resolve this issue? I have the same error on OSX running "pyadb shell". The .pub key should be valid.

You need to modify line 33 of sign_cryptography.py to add .encode('ascii') as follows:
sa_prv_file.read().encode('ascii'), None, default_backend())
