Sodium supports a variety of compilers and operating systems, including Windows (with MingW or Visual Studio, x86 and x64), iOS, Android, as well as Javascript and Webassembly.<\/p>\n<h2>Installing libsodium Software Library for Encryption<\/h2>\n<p>Sodium is a shared library with a machine-independent set of headers, so that it can easily be used by 3rd party projects. The library is built using autotools, making it easy to package. Installation is trivial, and both compilation and testing can take advantage of multiple CPU cores.<\/p>\n<p>Download a tarball of libsodium, preferably the latest stable version, then follow the ritual:<\/p>\n<pre>.\/configure\r\nmake && make check\r\nsudo make install<\/pre>\n<p>Since different files are compiled for different CPU classes, and to prevent unwanted optimizations, avoiding link-time optimization (LTO) is recommended. On Linux, if the process hangs at the <code>make check<\/code> step, your system PRG may not have been properly seeded. Please refer to the notes in the &#8220;Usage&#8221; section for ways to address this.<\/p>\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3033787195489589\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<!-- Darknet Responsive Post Ad Links [previously link ad unit] -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-client=\"ca-pub-3033787195489589\"\r\n     data-ad-slot=\"5456620019\"\r\n     data-ad-format=\"auto\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script>\n<h3>Using libsodium Encryption Library<\/h3>\n<p>A project using libsodium should include the <code>sodium.h<\/code> header.
