keyring_create.R

library(keyring)

# Set variables to be used in keyring.
kr_name <- "my_keyring"
kr_service <- "my_database"
kr_username <- "my_username"

# Create a keyring and add an entry using the variables above
kb <- keyring::backend_file$new()
# Prompt for the keyring password, used to unlock keyring
kb$keyring_create(kr_name)
# Prompt for the password to be stored in the keyring
kb$set(kr_service, username=kr_username, keyring=kr_name)
# Lock the keyring
kb$keyring_lock(kr_name)

# The encrypted keyring file is now stored at ~/.config/r-keyring/ and can be
# accessed by any R program that provides the keyring password
