R Documentation

Store SMTP credentials in the system's key-value store

Description

We can set SMTP access credentials in the system-wide key-value store for the purpose of more easily sending email messages through smtp_send(). With this key added, the credentials helper creds_key() can be used in the credentials argument of smtp_send() (the id value is used to unambiguously refer to each key).

Usage

create_smtp_creds_key(
  id,
  user = NULL,
  provider = NULL,
  host = NULL,
  port = NULL,
  use_ssl = NULL,
  overwrite = FALSE
)

Arguments

`id`	An identifying label for the keyname. The full key name is constructed in the following way: `⁠blastula-v1-<id>⁠`. This `id` value is what's needed later to either use the key with `creds_key()`, or, delete the key with `delete_credential_key()`. A single, non-`NA` character, numeric, or integer value can be supplied here; the `id` will be coerced to a character value. If the `id` is supplied as a single character value, it cannot be an empty string and it cannot include hyphen characters.
`user`	The username for the email account. Typically, this is the email address associated with the account.
`provider`	An optional email provider shortname for autocompleting SMTP configuration details (the `host`, `port`, `use_ssl` options). Options currently include `gmail`, `outlook`, and `office365`. If nothing is provided then values for `host`, `port`, and `use_ssl` are expected.
`host`, `port`, `use_ssl`	Configuration info for the SMTP server. The `host` and `port` parameters are the address and port for the SMTP server. `use_ssl` is an option as to whether to allow the use of STARTTLS, if available: it should be `TRUE` unless you have a specific reason to set it to `FALSE`.
`overwrite`	An option that controls the overwriting of existing keys with the same `id` value. By default, this is `FALSE` (where overwriting is prohibited).

Details

Support for setting keys through create_smtp_creds_key() is provided through the keyring package. This function cannot be used without that package being available on the system. We can use install.packages("keyring") to install keyring.

Examples

# Store SMTP credentials using the
# system's secure key-value store to
# make it much easier to send email
# out through Gmail with `smtp_send()`;
# provide the `id` of "gmail_creds"

# create_smtp_creds_key(
#   id = "gmail_creds",
#   provider = "gmail",
#   user = "user_name@gmail.com",
#   )
