'Blowfish' Key Derivation and Password Hashing

Bindings to the 'blowfish' password hashing algorithm < https://www.openbsd.org/papers/bcrypt-paper.pdf> derived from the 'OpenBSD' implementation.

Spherical Geometry Operators Using the S2 Geometry Library

Provides R bindings for Google's s2 library for geometric calculations on the sphere. High-performance constructors and exporters provide high compatibility with existing spatial packages, transformers construct new geometries from existing geometries, predicates provide a means to select geometries based on spatial relationships, and accessors extract information about geometries.

GNU Privacy Guard for R

Bindings to GnuPG for working with OpenGPG (RFC4880) cryptographic methods. Includes utilities for public key encryption, creating and verifying digital signatures, and managing your local keyring. Some functionality depends on the version of GnuPG that is installed on the system. On Windows this package can be used together with 'GPG4Win' which provides a GUI for managing keys and entering passphrases.

Bindings to 'OpenCV' Computer Vision Library

Exposes some of the available 'OpenCV' < https://opencv.org/> algorithms, such as a QR code scanner, and edge, body or face detection. These can either be applied to analyze static images, or to filter live video footage from a camera device.

Google's Compact Language Detector 3

Google's Compact Language Detector 3 is a neural network model for language identification and the successor of 'cld2' (available from CRAN). The algorithm is still experimental and takes a novel approach to language detection with different properties and outcomes. It can be useful to combine this with the Bayesian classifier results from 'cld2'. See < https://github.com/google/cld3#readme> for more information.

A GraphQL Query Parser

Bindings to the 'libgraphqlparser' C++ library. Parses GraphQL < https://graphql.org> syntax and exports the AST in JSON format.

Read, Write, and Modify TOML Files

Simple toolkit for working with TOML text. Based on tomledit which allows for modifying TOML while preserving order, comments,and whitespace.

Bindings to AppArmor and Security Related Linux Tools

Bindings to kernel methods for enforcing security restrictions. AppArmor can apply mandatory access control (MAC) policies on a given task (process) via security profiles with detailed ACL definitions. In addition this package implements bindings for setting process resource limits (rlimit), uid, gid, affinity and priority. The high level R function 'eval.secure' builds on these methods to perform dynamic sandboxing: it evaluates a single R expression within a temporary fork which acts as a sandbox by enforcing fine grained restrictions without affecting the main R process. A portable version of this function is now available in the 'unix' package.

Fast and Simple Badge Generator

Bindings to 'badgen' < https://www.npmjs.com/package/badgen> to generate beautiful 'svg' badges in R without internet access. Images can be converted to 'png' using the 'rsvg' package as shown in examples.

Exploring and Testing the Toolchain and System Libraries

Helper functions that interface with the system utilities to learn about the local build environment. Lets you explore 'make' rules to test the local configuration, or query 'pkg-config' to find compiler flags and libs needed for building packages with external dependencies. Also contains tools to analyze which libraries that a installed R package linked to by inspecting output from 'ldd' in combination with information from your distribution package manager, e.g. 'rpm' or 'dpkg'.
