README.md

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

Build Status

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.

You can’t perform that action at this time.
