create_package_vault: Create a vault, as a folder or in an R package.

In secret: Share Sensitive Information in R Packages

Description

A vault is a folder that contains information about users and the secrets they share. You can create a vault as either a standalone folder, or as part of a package.

Usage

create_package_vault(path = ".")

create_vault(path)

Arguments

path	Path to the R package. A file or directory within the package is fine, too. If the vault directory already exists, a message is given, and the function does nothing.

Details

A vault is a folder with a specific structure, containing two directories: users and secrets.

In users, each file contains a public key in PEM format. The name of the file is the identifier of the key, an arbitrary name. We suggest that you use email addresses to identify public keys. See also add_user().

In secrets, each secret is stored in its own directory. The directory of a secret contains

1. the secret, encrypted with its own AES key, and

2. the AES key, encrypted with the public keys of all users that have access to the secret, each in its own file.

To add a secret, see add_secret()

Value

The directory of the vault, invisibly.

Creating a package folder

When you create a vault in a package, this vault is stored in the inst/vault directory of the package during development. At package install time, this folder is copied to the vault folder.

Examples

## Not run: 
# The `secret` package contains some user keys for demonstration purposes.
# In this example, Alice shares a secret with Bob using a vault.

keys <- function(x){
  file.path(system.file("user_keys", package = "secret"), x)
}
alice_public  <- keys("alice.pub")
alice_private <- keys("alice.pem")
bob_public  <- keys("bob.pub")
bob_private <- keys("bob.pem")
carl_private <- keys("carl.pem")

# Create vault

vault <- file.path(tempdir(), ".vault")
if (dir.exists(vault)) unlink(vault) # ensure vault is empty
create_vault(vault)

# Add users with their public keys

add_user("alice", public_key = alice_public, vault = vault)
add_user("bob", public_key = bob_public, vault = vault)
list_users(vault = vault)

# Share a secret

secret <- list(username = "user123", password = "Secret123!")

add_secret("secret", value = secret, users = c("alice", "bob"),
           vault = vault)
list_secrets(vault = vault)

# Alice and Bob can decrypt the secret with their private keys
# Note that you would not normally have access to the private key
# of any of your collaborators!

get_secret("secret", key = alice_private, vault = vault)
get_secret("secret", key = bob_private, vault = vault)

# But Carl can't decrypt the secret

try(
  get_secret("secret", key = carl_private, vault = vault)
)

# Unshare the secret

unshare_secret("secret", users = "bob", vault = vault)
try(
  get_secret("secret", key = bob_private, vault = vault)
)


# Delete the secret

delete_secret("secret", vault = vault)
list_secrets(vault)

# Delete the users

delete_user("alice", vault = vault)
delete_user("bob", vault = vault)
list_users(vault)
