JMSwag asked me to report this error here (Please report to python-ed25519. I get the same error when I execute ed25519 from the repl.), this is in reference of the fololwing issue:
Digital-Sapphire/PyUpdater#45

How to reproduce:

pip install -U https://github.com/JMSwag/PyUpdater/tarball/master

I'm having the same issue--

Steps to reproduce:

>>> import ed25519
>>> ed25519.create_keypair()

@soundstripe @marcelomanzo Same here, any idea how to fix? To be fair I couldn't create any keys so I did: if ns.create is True and False: Rather than just True
log.error('You can not create off-line keys on your dev machine')
return

Same problem, Windows 10, python 3.6.4. Is there any idea how to fix it?

I'm getting the same as OP with PyUpdater.

I am on Windows 10, Python 3.7.2 from Anaconda.

I can do one of the above examples fine:

>>> ed25519.create_keypair()
(<ed25519.keys.SigningKey at 0x2684de57160>, <ed25519.keys.VerifyingKey at 0x2684de57208>)

But I get the same error as OP with the call to publickey.

Here's a bit of PyUpdater code that leads to the error:

def _add_sig(self):
    # Adding new signature to version file
    # Raw private key will need to be converted into
    # a signing key object
    private_key_raw = self._load_private_keys()
    if private_key_raw is None:
        log.error('Private Key not found. Please '
                  'import a keypack & try again')
        return

    # Load update manifest
    update_data = self._load_update_data()

    # We don't want to verify the signature
    if 'signature' in update_data:
        log.debug('Removing signatures from version file')
        del update_data['signature']

    # We create a signature from the string
    update_data_str = json.dumps(update_data, sort_keys=True)

    private_key_raw = private_key_raw.encode('utf-8')

    # Creating signing key object
    private_key = ed25519.SigningKey(private_key_raw,
                                     encoding=self.key_encoding)

This makes me wonder if it's something with the inputs to SigningKey - either the private_key_raw or the key_encoding. key_encoding is set to 'base64'.

Downgraded to Python 3.6.0 and this solved it for me.

[okready]

I opened a PR (#14) for what I believe fixes the issue. It seems to only occur with 64-bit versions of Python on Windows; 32-bit versions of Python (regardless of whether Windows itself is 32-bit or 64-bit) appear to be unaffected by the bug.

For anyone who tried downgrading, do you recall whether you switched to a 32-bit version of Python in the process?

[warner]

I just released version 1.5 with that fix.. sorry it took so long. Could someone with an affected system give the new version a try and let me know if it works now?

[JMSwag]

@warner 1.5 works without issue. Thanks!
