Ensure you know the location of your public and private keys. In Linux this is usually the folder
~/.ssh, so on Windows you may want to choose the same folder.
By default, the package looks for your private key at
You can change this default by setting an environment variable
# This is optional - only do this if you want to change the default location Sys.setenv(USER_KEY = "path/to/private/key")
Test that the package can read your key. This might fail if you don’t have a key at
~/.ssh/id_rsa, or if your private key has a pass phrase and R in running in non-interactive mode.
library(secret) try(local_key(), silent = TRUE)
You can create a vault by using
vault <- file.path(tempdir(), ".vault") dir.create(vault) create_vault(vault)
A vault consists of two folders for:
users: contains user and their public keys
secrets: contains the encrypted secrets
##  "README" "secrets" "users"
Alternatively, you can create a vault in an R package:
pkg_root <- "/path/to/package" create_package_vault(pkg_root)
To add a user to the vault, you have to know their public key.
secret package contains some public and private keys you can use for demonstration purposes.
key_dir <- file.path(system.file(package = "secret"), "user_keys") alice_public_key <- file.path(key_dir, "alice.pub") alice_private_key <- file.path(key_dir, "alice.pem") openssl::read_pubkey(alice_public_key)
## [2048-bit rsa public key] ## md5: 1d858d316afb8b7d0efd69ec85dc7174
Add the public key of Alice to the vault:
add_user("alice", alice_public_key, vault = vault)
A secret can be any R object - this object will be serialised and then encrypted to the vault.
secret_to_keep <- c(password = "my_password") add_secret("secret_one", secret_to_keep, users = "alice", vault = vault)
You can decrypt a secret if you have the private key that corresponds to the public key that was used to encrypt the secret,
get_secret("secret_one", key = alice_private_key, vault = vault)
## password ## "my_password"
If you use windows, you most likely created your keys using PuttyGen. Note that the key created by default from PuttyGen is not in OpenSSH format, so you have to convert your format first. To do this, use the
/Conversions/Export OpenSSH key menu item in PuttyGen.
Note that the folder
~/.ssh in Windows usually expands to
C:\\Users\\YOURNAME\\Documents\\.ssh. You can find the full path by using:
normalizePath("~/.ssh", mustWork = FALSE)
##  "/Users/gaborcsardi/.ssh"
