python libsodium wrapper

This is a very simple wrapper around libsodium masquerading as nacl.

[](https://travis-ci.org/stef/pysodium)

This wrapper requires a pre-installed libsodium from:

https://github.com/jedisct1/libsodium

then it provides access to the following functions:

Note

most of the the *_easy functions are not implemented as the “non-easy” functions provide already the “easy” interface, which hides the placement of buffers in memory, which makes little sense in python, so this wrapper handles this.
