Add configuration to handle custom certificate

[Akendo]

HI,

First of all, thanks for this project!

I'm using my certificate from task warrior to handle this. I wish I could change this parameter within the configuration file to point to the given file instead of the hard-coded public_key.pem or private_key.pem files.

Maybe I'm holding it wrong, but if otherwise, it should be documented.

Thanks anyway,
best regards

Hi Akendo,

reusing and supporting Taskwarrior certificates sounds like a useful addition!

Unfortunately, I am not an expert in cryptography. Before promoting this, I would like to make sure that the certificates used are compatible.

If someone has a good resource to better understand PEM files, certificates and keys, please let me know!

Your answer surprises me a bit, considering the fact that you're using JWT, which requires asymmetric types of keys.

As long your certificate is x509 compilable, this shouldn't be much of a concern. PEM files are just a coding format to contain the x and y ( y which is often quite static away) parameters of your asymmetric keys, with some additional PKI information. What is relevant for us at this stage is the key/certificate.

So, it might be necessary to add also key size and format to the configuration?

I might need to review your usage of JWT. So far, it seems to more like you copy and pasted the default example with slight adjustments.
