This is python wrapper for curve25519 library with ed25519 signatures. The C code was pulled from [libaxolotl-android](https://github.com/WhisperSystems/libaxolotl-android)
At the moment this wrapper is meant for use by [python-axolotl](http://github.com/tgalal/python-axolotl) and provides the following methods only:
```python
import axolotl_curve25519 as curve
import os
randm32 = os.urandom(32)
randm64 = os.urandom(64)
private_key = curve.generatePrivateKey(randm32)
public_key = message = curve.generatePublicKey(private_key)
agreement = curve.calculateAgreement(private_key, public_key)
signature = curve.calculateSignature(randm64, private_key, message)
verified = curve.verifySignature(public_key, message, signature) == 0
```
# Installation
## Linux
You need to have python headers installed, usually through installing package called python-dev, then as superuser run:
```
python setup.py install
```
## Windows
- Install [mingw](http://www.mingw.org/) compiler
- Add mingw to your PATH
- In PYTHONPATH\Lib\distutils create a file called distutils.cfg and add these lines:
