Access the System Credential Store from R

Platform independent 'API' to access the operating system's credential store. Currently supports: 'Keychain' on 'macOS', Credential Store on 'Windows', the Secret Service 'API' on 'Linux', and a simple, platform independent store implemented with environment variables. Additional storage back-ends can be added easily.

Platform independent API to access the operating systems credential store. Currently supports:

  • Keychain on macOS,
  • Credential Store on Windows,
  • the Secret Service API on Linux, and
  • environment variables on all platforms. Additional storage backends can be added easily.

Installation

Linux

Install the libsecret library, at least version 0.16.

  • Debian/Ubuntu: libsecret-1-dev
  • Recent RedHat, Fedora and CentOS systems: libsecret-devel

OS X and Windows

No additional software needed

R package

source("https://install-github.me/r-lib/keyring")

Usage

Configuring an OS-specific backend:

  • The default is operating system specific, and is described in manual page of default_backend(). In most cases you don't have to configure this.
  • MacOS: backend_macos
  • Linux: backend_secret_service
  • Windows: backend_wincred
  • Or store the secrets in environment variables on other operating systems: backend_env

Query secret keys in a keyring:

Each keyring can contain one or many secrets (keys). A key is defined by a service name and a password. Once a key is defined, it persists in the keyring store of the operating system. This means the keys persist beyond the termination of and R session. Specifically, you can define a key once, and then read the key value in completely independent R sessions.

  • Setting a secret interactively: key_set()
  • Setting a secret from a script, i.e. non-interactively: key_set_with_value()
  • Reading a secret: key_get()
  • Listing secrets: key_list()
  • Deleting a secret: key_delete()

Managing keyrings:

A keyring is a collection of keys that can be treated as a unit. A keyring typically has a name and a password to unlock it. See keyring_create(), keyring_delete(), keyring_list(), keyring_lock(), keyring_unlock(), keyring_is_locked().

Note that all platforms have a default keyring, and key_get(), etc. will use that automatically. The default keyring is also convenient, because the OS unlocks it automatically when you log in, so secrets are available immediately.

You only need to explicitly deal with keyrings and the keyring_* functions if you want to use a different keyring.
