`rdp-rs` is a pure Rust implementation of Microsoft Remote Desktop Protocol.
`rdp-rs` is delivered with an client implementation named `mstsc-rs`.
This crate is focus on security, and address user who wants a safe client, or security researcher that want to play with RDP.
## Why ?
On one side, Remote Desktop Protocol is a complex protocol, and it's hard to play easily with it.
I've already implemented RDP in [Python](https://github.com/citronneur/rdpy) and [Javascript](https://github.com/citronneur/node-rdpjs) with an event driven pattern.
It appears that this kind of pattern raise the complexity of the library, and at the end there is a lot of bugs and no PR, and nobody can't play with RDP in deeper.
On other side, there is no *secure* implementation of the RDP protocol open sourced.
In the end, I would like to build a highly secure, cross-platform and highly customizable client.
## Install
To use the `rdp-rs` as library in your project, add the following to `Cargo.toml`:
```
[dependencies]
rdp-rs = "0.1.0"
```
You can install binaries through cargo :
```
cargo install rdp-rs --features=mstsc-rs
mstsc-rs --help
```
For windows platform, there is some prebuilt binaries in [release](https://github.com/citronneur/rdp-rs/releases) session.
## Play with `mstsc-rs`
`mstsc-rs` is a RDP client, based on `rdp-rs` crate. It's cross platform and highly customizable :
```
mstsc-rs 0.1.0

Secure Remote Desktop Client in RUST
USAGE:
mstsc-rs.exe [FLAGS] [OPTIONS]
FLAGS:
--admin Restricted admin mode
--auto AutoLogon mode in case of SSL nego
--blank Do not send credentials at the last CredSSP payload
--check Check the target SSL certificate
--ssl Disable Netwoek Level Authentication and only use SSL
-h, --help Prints help information
-V, --version Prints version information
OPTIONS:
--dom <domain> Windows domain [default: ]
--hash <hash> NTLM Hash
--height <height> Screen height [default: 600]
--layout <layout> Keyboard layout: us or fr [default: us]
--name <name> Name of the client send to the server [default: mstsc-rs]
--pass <password> Password [default: ]
--port <port> Destination Port [default: 3389]
--target <target> Target IP of the server
--user <username> Username [default: ]
--width <width> Screen width [default: 800]
```
`mstsc-rs` have been tested to connect to server that ran from Windows 7 to Windows 10.
### Basic connection (using Network Level Authentication over SSL)
By default `mstsc-rs` use NLA as authentication protocol :
```
mstsc-rs --target IP --user foo --pass bar --dom enterprise
```
### Basic connection (using SSL without NLA)
You can disable nla with the `ssl` option, but if you want to logon with credentials, you need to specify the `auto` option :
```
mstsc-rs --target IP --user foo --pass bar --ssl --auto
```
### Pass the hash (using restricted admin mode)
Microsoft recently add some new feature for the NLA authentication. One of them is Restricted Admin Mode.
This mode allow an admin to use the `Network` authentication as `Interactive` authentication. This mode allow an admin to be authenticate only by its NTLM hash.
```
mstsc-rs --target IP --user foo --hash a4c37e22527cc1479a8d620d2953b6c0 --admin
```
### Check already logon User
In certain case, it's useful to use SSL in order to NLA.
When server doesn't enforce NLA, using SSL allow to view which users are connected on the server without steal the session :
```
mstsc-rs --target IP --ssl
```
When NLA is enforced, You can check opened or available session by sending blank credentials for the `Interactive` authentication by using the `blank` option :
```
mstsc-rs --target IP --user foo --pass bar --blank
```
### Tamper the client name
A RDP client send the client name. `mstsc-rs` allow a user to customize it :
```
mstsc-rs --target IP --user foo --pass bar --name mstsc
```
### Tamper LogonType=10 to LogonType=7
When you mix `blank` option and `auto` option on a NLA session, that will lead to logon without emitted `4624` with `LogonType=10` but with `LogonType=7` :
```
mstsc-rs --target IP --user foo --pass bar --blank --auto
```
## Play with `rdp-rs` crate
`rdp-rs` is designed to be easily integrated into Rust environment.
If you want to connect using normal credentials and NLA:
```rust
use std::net::{SocketAddr, TcpStream};
use rdp::core::client::Connector;
use rdp::core::event::{RdpEvent, PointerEvent, PointerButton};
let addr = "192.168.0.1:3389".parse::<SocketAddr>().unwrap();
let tcp = TcpStream::connect(&addr).unwrap();
let mut connector = Connector::new()
.screen(800, 600)
.credentials("domain".to_string(), "username".to_string(), "password".to_string());
let mut client = connector.connect(tcp).unwrap();
```
Now you want to send an input, a mouse for example :
```rust
client.write(RdpEvent::Pointer(
// Send a mouse click down at 100x100
PointerEvent {
x: 100 as u16,
y: 100 as u16,
button: PointerButton::Left,
down: true
}
)).unwrap()
```
Now you want to receive an event from server, a bitmap event for example:
```rust
RdpEvent::Bitmap(bitmap) => {
// do something with bitmap
}
_ => println!("Unhandled event")
}
}).unwrap()
```
