To implement a new keyring backend, you need to inherit from this class and then redefine the get, set, set_with_value and delete methods. Implementing the list method is optional. Additional methods can be defined as well.


These are the semantics of the various methods:

get(service, username = NULL, keyring = NULL)
get_raw(service, username = NULL, keyring = NULL)
set(service, username = NULL, keyring = NULL, prompt = "Password: ")
set_with_value(service, username = NULL, password = NULL,
               keyring = NULL)
set_with_raw_value(service, username = NULL, password = NULL,
               keyring = NULL)
delete(service, username = NULL, keyring = NULL)
list(service = NULL, keyring = NULL)

What these functions do:

  • get() queries the secret in a keyring item.

  • get_raw() is similar to get(), but returns the result as a raw vector.

  • set() sets the secret in a keyring item. The secret itself is read in interactively from the keyboard.

  • set_with_value() sets the secret in a keyring item to the specified value.

  • set_with_raw_value() sets the secret in keyring item to the byte sequence of a raw vector.

  • delete() remotes a keyring item.

  • list() lists keyring items.

The arguments:

  • service String, the name of a service. This is used to find the secret later.

  • username String, the username associated with a secret. It can be NULL, if no username belongs to the secret. It uses the value of the keyring_username, if set.

  • keyring String, the name of the keyring to work with. This only makes sense if the platform supports multiple keyrings. NULL selects the default (and maybe only) keyring.

  • password The value of the secret, typically a password, or other credential.

  • prompt String, the text to be displayed above the textbox.
