We are pleased to announce the first public release of
vaultr, our R client for HashiCorp’s “vault”, a system for storing secrets and sensitive data and enabling these secrets to be used in applications.
Vault (the server) is a little like a password manager (e.g., LastPass or Bitwarden) but designed for use within applications, rather than for storing personal passwords. With vault, you can have a central source of secrets and sensitive data (ssh keys, database passwords, ssl certificates) that can be used when deploying or using applications. This makes it much easier to avoid writing these secrets to disk in plain text while still allowing automated use of secrets.
vaultr, logging-in, writing and reading a secret from a central store can be done with very little code:
vault <- vaultr::vault_client(login = TRUE) vault$write("/secret/database/users/readonly", list(password = "s3cret!")) vault$read("/secret/database/users/readonly") #> $password #>  "s3cret!"
This package allows access to a large fraction of vault’s api, including:
- Authentication via username/password, via GitHub, as well as an “AppRole” method (designed for machine-based authentication)
- Secrets stored in two key-value stores (one simple and unversioned, the other allowing versioning and metadata), the cubbyhole storage system for token-scoped secrets, and vault’s transit engine for “encryption-as-a-service”.
In order to develop R packages that use vault, we have added support for starting and controlling vault servers in “Dev” server mode.
vaultr is now available from CRAN and can be installed with
