Hi,
I'm trying to load a previously saved private key into a JWK instance using the JWK.load method.
The documentation (https://josepy.readthedocs.io/en/latest/api/jwk/) indicates that the load method expects a str to be passed to the data object, but whenever I do this, I'm getting an exception, resulting in the next stacktrace:
File "C:/Users/xxx/Desktop/xxx/certificate_requester.py", line 13, in __main__
key = jose.JWK.load(data=private_key)
File "C:\Users\xxx\Desktop\xxx\venv\lib\site-packages\josepy\jwk.py", line 108, in load
key = cls._load_cryptography_key(data, password, backend)
File "C:\Users\xxx\Desktop\xxx\venv\lib\site-packages\josepy\jwk.py", line 83, in _load_cryptography_key
return loader(data, backend)
File "C:\Users\xxx/\Desktop\xxx\venv\lib\site-packages\cryptography\hazmat\primitives\serialization.py", line 24, in load_pem_public_key
return backend.load_pem_public_key(data)
File "C:\Users\xxx/\Desktop\xxx\venv\lib\site-packages\cryptography\hazmat\backends\openssl\backend.py", line 1019, in load_pem_public_key
mem_bio = self._bytes_to_bio(data)
File "C:\Users\xxx\Desktop\xxx\venv\lib\site-packages\cryptography\hazmat\backends\openssl\backend.py", line 437, in _bytes_to_bio
data_char_p = self._ffi.new("char[]", data)
TypeError: initializer for ctype 'char[]' must be a bytes or list or tuple, not str
However, when I pass in a bytes object (obtained by performing an encode('ascii') on the str instance, it's working out all fine.
Could this be due to a difference between python2 and python 3? I'm using the latter.
Environment:
- acme 0.21.1
- josepy 1.0.1
- python 3.6.3
