Use key as string without a temporary file

[ssigwart]

• Addresses Accept key content directly instead of require a key file #1007
• This allows you to use a private key from a string without writing to a temporary file. For security reasons, I'd rather not have the key written to disk on the server.

I think we are removing the ability to use a password against the private key here. Is it possible to change this to accommodate this? Thanks for your submission.

[ssigwart]

Thanks for looking @Sephster. I think my change addresses your comment.

[ssigwart]

@Sephster, is there anything I should do to get this merged?

[ssigwart]

@Sephster, there are merge conflicts now. Should I rebase and resolve them?

[Sephster]

That would be appreciated cheers. I've been tidying up a personal project but hoping to get back to this within the week. Thanks very much

[ssigwart]

Thanks, @Sephster. I rebased it and fixed the conflicts.

[Sephster]

@ssigwart would it be possible for you to resolve the conflict? I tried to do this myself but don't have write access to your branch. There is also a trailing comma on line 80 of the BearerToken file which is causing issues in PHP 7.2. Everything else looks good so happy to merge in once this is resolved. Thank you

[ssigwart]

@Sephster, I fixed the trailing comma and rebased to fix the conflict. Thanks!

[Sephster]

Thanks @ssigwart - looks great.
