Binary to connect with a remote machine to edit files and run programs.
🚧 **(Alpha stage software) This program is in rapid development and may break or change frequently!** 🚧
## Details
The `distant` binary supplies both a server and client component as well as
a command to start a server and configure the local client to be able to
talk to the server.
- Asynchronous in nature, powered by [`tokio`](https://tokio.rs/)
- Data is serialized to send across the wire via [`CBOR`](https://cbor.io/)
- Encryption & authentication are handled via [`orion`](https://crates.io/crates/orion)
- [XChaCha20Poly1305](https://cryptopp.com/wiki/XChaCha20Poly1305) for an authenticated encryption scheme
- [BLAKE2b-256](https://www.blake2.net/) in keyed mode for a second authentication
- [Elliptic Curve Diffie-Hellman](https://en.wikipedia.org/wiki/Elliptic-curve_Diffie%E2%80%93Hellman) (ECDH) for key exchange
## Installation
### Prebuilt Binaries
If you would like a pre-built binary, check out the
[releases section](https://github.com/chipsenkbeil/distant/releases).
### Building from Source
If you have [`cargo`](https://github.com/rust-lang/cargo) installed, you can
directly download and build the source via:

cargo install distant
```
Alternatively, you can clone this repository and build from source following
the [build guide](./BUILDING.md).
## Examples
Launch a remote instance of `distant` by SSHing into another machine and
starting the `distant` executable:
```bash
# Connects to my.example.com on port 22 via SSH to start a new session
distant launch my.example.com
# After the session is established, you can perform different operations
# on the remote machine via `distant action {command} [args]`
distant action copy path/to/file new/path/to/file
distant action run -- echo 'Hello, this is from the other side'
