In this branch I'm gonna cover by tests all the crypto functions used in code and do a refactoring. Basic points:

only highlevelcrypto should import from pyelliptic
highlevelcrypto should not depend on the app state e.g. module state or BMConfigparser() instance (the same will be done for protocol in #1788)
highlevelcrypto should include hashes - double sha512, ripemd160
finally I'm gonna detach pyelliptic into the separate repo to show a possible way of addressing #886

these binary data should also be a variable in samples.

ideally b'hello' should also be a variable in samples

ideally `b'hello'` should also be a variable in samples

overall nice work, although I haven't investigated it in depth

It seems that I misplaced (or misnamed) the signatures. I was going to regenerate them. And there is also a lot of unfinished changes here, mentioned in the PR description.

I'm not sure if these functions should return the pair or only the private key.
