pk.get_supported_curves raise `ValueError: b'x25519' is not a valid Curve` about python-mbedtls

This bug prevents any use of pk.ECC.* functions, as they often call get_supported_curves internally.

Tried downgrading mbedtls to 2.26.0, didn't help.

Hi Marián,

Could you try again with 2.16? It would be too much work for me to support anything but LTS versions from upstream and the library is not tested with anything else.

I do not use brew but if you need help to install the library from source, feel free to use

• https://github.com/Synss/python-mbedtls/blob/master/scripts/download-mbedtls.sh
• https://github.com/Synss/python-mbedtls/blob/master/scripts/install-mbedtls.sh

These scripts should work on MacOS.

Cheers,
Mathias

I can confirm that downgrading to 2.16.9 works. Thanks for your help.

Can you update README file and specify, that the 2.16 is the latest supported version? It would be a solution for #46 , at least for now. Homebrew on macOS consider 3.0.0 as the latest, other users might have the same problem.
