Description

Retrieve a secret from the vault.

Usage

1
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.
