libsodium-net, or better said, libsodium for .NET, is a C# wrapper around libsodium. For those that don't know, libsodium is a portable implementation of Daniel Bernstein's fantastic NaCl library. If you aren't familiar with NaCl, I highly suggest that you look into libsodium and NaCl before using this library.
This library can be built in Visual Studio 2010, Xamarin Studio (MonoDevelop 3.x supported), and targets .NET 4.0; it is compiled against libsodium v1.0.7.
On OSX & Linux, your copy of libsodium must be compiled for the same architecture as your copy of Mono. If you are running a 32bit process, your copy of libsodium must be 32bit as well.
Any method that takes a String, has an overload that accepts a byte array; Strings are assumed to be UTF8; if this is not the case, please convert it to bytes yourself and use the overloads that accept byte arrays.
libsodium requires the Visual C++ Redistributable for Visual Studio 2015.
Starting with version 0.4.0, all files are signed via a Certum.pl Code Signing certificate. The files are signed under the name
Open Source Developer, Adam Caudill - this can be used to ensure that the files haven't been altered.
