It is a portable, cross-compilable, installable, packageable fork of [NaCl](http://nacl.cr.yp.to/), with a compatible API, and an extended API to improve usability even further. Its goal is to provide all of the core operations needed to build higher-level cryptographic tools. 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. ## Documentation The documentation is available on Gitbook and built from the [libsodium-doc](https://github.com/jedisct1/libsodium-doc) repository: * [libsodium documentation](https://download.libsodium.org/doc/) - online, requires Javascript. * [offline documentation](https://www.gitbook.com/book/jedisct1/libsodium/details) in PDF format. ## Integrity Checking The integrity checking instructions (including the signing key for libsodium) are available in the [installation](https://download.libsodium.org/doc/installation#integrity-checking) section of the documentation. ## Community A mailing-list is available to discuss libsodium. In order to join, just send a random mail to `sodium-subscribe` {at} `pureftpd` {dot} `org`. ## License [ISC license](https://en.wikipedia.org/wiki/ISC_license).
