Bindings to AppArmor and Security Related Linux Tools
Bindings to various methods in the kernel 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 the package has kernel bindings for setting the process hardware resource limits (rlimit), uid, gid, affinity and priority. The high level R function 'eval.secure' builds on these methods to do 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. Recent versions on this package can also be installed on systems without libapparmor, in which case some features are automatically disabled.
A collection of specifications to securely transfer claims such as authorization information between parties. A JSON Web Token (JWT) contains claims used by systems to apply access control rules to its resources. One potential use case of the JWT is authentication and authorization for a system that exposes resources through OAuth 2.0.
Toolkit for Encryption, Signatures and Certificates Based on OpenSSL
Bindings to OpenSSL libssl and libcrypto, plus custom SSH pubkey parsers. Supports RSA, DSA and EC curves P-256, P-384 and P-521. Cryptographic signatures can either be created and verified manually or via x509 certificates. AES can be used in cbc, ctr or gcm mode for symmetric encryption; RSA for asymmetric (public key) encryption or EC for Diffie Hellman. High-level envelope functions combine RSA and AES for encrypting arbitrary sized data. Other utilities include key generators, hash functions (md5, sha1, sha256, etc), base64 encoder, a secure random number generator, and 'bignum' math methods for manually performing crypto calculations on large multibyte integers.
R Client for Ohmage 2 server
R Client for Ohmage 2 server. Implements basic R functions to retrieve and process data.
'Blowfish' Password Hashing Algorithm
An R interface to the OpenBSD 'blowfish' password hashing algorithm, as described in "A Future-Adaptable Password Scheme" by Niels Provos. The implementation is derived from the 'py-bcrypt' module for Python which is a wrapper for the OpenBSD implementation.
'Markdown' Rendering for R
Provides R bindings to the 'Sundown' 'Markdown' rendering library ( https://github.com/vmg/sundown). 'Markdown' is a plain-text formatting syntax that can be converted to 'XHTML' or other formats. See http://en.wikipedia.org/wiki/Markdown for more information about 'Markdown'.
R Interface to the 'Protocol Buffers' 'API' (Version 2 or 3)
Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. Google uses Protocol Buffers for almost all of its internal 'RPC' protocols and file formats. Additional documentation is available in two included vignettes one of which corresponds to our paper in the Journal of Statistical Software (2016, v71i02). Either version 2 or 3 of the 'Protocol Buffers' 'API' is supported.
Classes for 'GeoJSON'
Classes for 'GeoJSON' to make working with 'GeoJSON' easier. Includes S3 classes for 'GeoJSON' classes with brief summary output, and a few methods such as extracting and addin bounding boxes, properties, and coordinate reference systems; linting through the geojsonlint package; and serializing to/from Geobuf binary 'GeoJSON' format.
