## sendafriend
|
||||
|
||||
quickly send files between machines by piping them on the command line, with bidirectional authentication and metadata resistance via tor (built on cwtch)
|
||||
|
||||
includes a way to quickly exchange onion addresses using a low-entropy shared secret (using pairwise socialist millionaires' protocol on a bbs)
|
||||
|
||||
note that we only support files up to 64k right now, sorry :( (a fix for this is in the works)
|
||||
|
||||
## installation
|
||||
|
||||
requires you to have go installed and your gopath configured correctly (sorry)
|
||||
|
||||
`go get openprivacy.ca/openprivacy/sendafriend`
|
||||
|
||||
## usage
|
||||
|
||||
one-time setup, on both machines:
|
||||
`sendafriend pair [make-up-a-name]`
|
||||
|
||||
activate the receiver first:
|
||||
`sendafriend receive [made-up-name] > file.ext`
|
||||
|
||||
then the sender:
|
||||
`sendafriend send [made-up-name] < file.ext`
|
||||
