Skip to contents

First, the content (a file) is encrypted and packed and then shipped to the recipient using the specified vessel (transportation method). If the given vessel is not available the function return an error. Optionally, a declaration can also be associated with the shipment and dispatched immediately after the actual cargo.


sship(content, recipient, pubkey_holder, vessel, declaration = "")

dispatch(recipient, vessel, cargo)

dispatchable(recipient, vessel)

make_url(recipient, vessel)

make_opts(recipient, vessel)



Character string: the full path to the file to be shipped


Character string: user name uniquely defining the recipient both in terms of the public key used for securing the content and any identity control upon docking. See also Details.


Character string: the holder of the (recipient's) public key. Currently, the only viable option here is 'github'.


Character string: means of transportation. Currently one of 'ssh' or 'ftp'.


Character string: the name of an empty file to be associated with shipment of the cargo itself and dispatched immediately after. The most likely use case is for the recipient to check for this file being present before picking up the cargo itself. Default value is "" in which case no declaration will be used.


Character vector: all items associated with the current shipment. Used only internally.


TRUE if successful


Most likely access control will be enforced before docking of the shipment can commence. For each recipient a list of available vessels (transport methods) is defined and must include relevant credentials. Functions used here rely on local configuration (sship.yml) to access such credentials.
