A Modern and Easy-to-Use Crypto Library
Bindings to 'libsodium': a modern, easy-to-use software library for encryption, decryption, signatures, password hashing and more. Sodium uses curve25519, a state-of-the-art Diffie-Hellman function by Daniel Bernstein, which has become very popular after it was discovered that the NSA had backdoored Dual EC DRBG.

Installation
Binary packages for OS-X or Windows can be installed directly from CRAN:
install.packages("sodium")
Installation from source on Linux or OSX requires libsodium. On Ubuntu 14.04 or lower use libsodium-dev from Launchpad:
sudo add-apt-repository -y ppa:chris-lea/libsodiumsudo apt-get update -qsudo apt-get install -y libsodium-dev
More recent Debian or Ubuntu install libsodium-dev directly from Universe:
sudo apt-get install -y libsodium-dev
On Fedora we need libsodium-devel:
sudo yum install libsodium-devel
On CentOS / RHEL we install libsodium-devel via EPEL:
sudo yum install epel-releasesudo yum install libsodium-devel
On OS-X use libsodium from Homebrew:
brew install libsodium
