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.

# Generate keypair:
key <- keygen()
pub <- pubkey(key)

# Encrypt message with pubkey
msg <- serialize(iris, NULL)
ciphertext <- simple_encrypt(msg, pub)

# Decrypt message with private key
out <- simple_decrypt(ciphertext, key)

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/libsodium
sudo apt-get update -q
sudo 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-release
sudo yum install libsodium-devel

On OS-X use libsodium from Homebrew:

brew install libsodium

On Solaris 10 we can have libsodium_dev from OpenCSW:

pkgadd -d http://get.opencsw.org/now
/opt/csw/bin/pkgutil -U
/opt/csw/bin/pkgutil -y -i libsodium_dev 
/usr/sbin/pkgchk -L CSWlibsodium-dev # list files
