get_secret: Retrieve a secret from the vault.

In secret: Share Sensitive Information in R Packages

Description

Retrieve a secret from the vault.

Usage

get_secret(name, key = local_key(), vault = NULL)

Arguments

name	Name of the secret.
key	The private RSA key to use. It defaults to the current user's default key.
vault	Vault location (starting point to find the vault). To create a vault, use create_vault() or create_package_vault(). If this is NULL, then secret tries to find the vault automatically: If the secret.vault option is set to path, that is used as the starting point. Otherwise, if the R_SECRET_VAULT environment variable is set to a path, that is used as a starting point. Otherwise the current working directory is used as the starting point. If the starting point is a vault, that is used. Otherwise, if the starting point is in a package tree, the inst/vault folder is used within the package. If no vault can be found, an error is thrown.

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)
