cryptography 1.4 Library Error on install

[qmontal]

Hey guys!

I know this project doesn't to seem to be developed currently, but just for you to be aware, on Ubuntu LTS 18.04 I am having issues when installing the dependencies, as cryptography is breaking (probably because of support from the latest openssl binaries).

I am installing cryptography 2.0, that is the earliest to not break and test the project with it.

Cheers!

I also get a breaking error with cryptography==1.4 as well:
