Trezor-crypto python binding

# Trezor-crypto python binding

This is the ctypes and cffi python binding for [trezor-crypto] used in Monero implementation.

The python module builds trezor-crypto as a shared library. Currently only ctypes is fully supported. CFFI module is built but the python method wrappers are not implemented yet (no the roadmap).

The module automatically generates the bindings from the [trezor-crypto] header files using [ctypeslib2] and [pycparser].

Note the forked version of the original trezor-crypto is used in order to support library mode (for now).

## Requirements:

• gcc / clang

• pkg-config

• libsodium

In order to use this module please install libsodium.

`bash sudo apt-get install libsodium-dev `

## Dev Requirements:

In order to generate bindings from the [trezor-crypto] header files the following tools are needed:

• clang

• ctypeslib2

• pycparser

• libclang.so / libclang.dylib

## Roadmap

• Code generate CFFI wrappers in the similar manner as ctype wrappers.

## Refresh Ctype bindings

In order to refresh method definitions and regenerate ctype wrappers from [trezor-crypto] header files run

`bash python trezor_crypto/cffi_build.py -a ctypes --debug `

## Refresh CFFI bindings

In order to refresh data/cffi.h from [trezor-crypto] header files run:

`bash python trezor_crypto/cffi_build.py -a cffi_h --debug `
