Introduction 👋

SuppaFTP is the main FTP/FTPS client library for Rust, with both support for sync/async programming and for all the FTP protocol features. It is a fork of the original ftp library "rust-ftp", but since the original library is currently unmaintained, I decided to keep working on this library by myself. Currently, I consider myself as the only maintainer of this project, indeed I've already added some features to the library and improved it with better error handling and test units.

Main differences between SuppaFTP and rust-ftp 🤔

  • Replaced OpenSSL with native-tls or rustls as you prefer 🔒
  • Added methods to work with streams (e.g. put_with_stream) ⬇️
  • suppaftp supports Active mode
  • Added get_welcome_msg method 👋
  • Supports for both sync/async rust 🕙
  • Supports for more commands 🌟
    • ABOR
    • APPE
    • REST
    • EPSV
    • EPRT
  • Some extra features, such as the LIST command output parser
  • Implementation of RFC 2428
  • Implementationb of RFC 2389
  • Removed deprecated statements ⚰️
  • Better error handling 🐛
  • Added test units keeping an eye on code coverage 👀

Get started 🏁

To get started, first add suppaftp to your dependencies:

suppaftp = "^6"


SSL/TLS Support

If you want to enable support for FTPS, you must enable the native-tls or rustls feature in your cargo dependencies, based on the TLS provider you prefer.

suppaftp = { version = "^6", features = ["native-tls"] }
# or
suppaftp = { version = "^6", features = ["rustls"] }

💡 If you don't know what to choose, native-tls should be preferred for compatibility reasons. ❗ If you want to link libssl statically, enable feature native-tls-vendored

Async support

If you want to enable async support, you must enable async feature in your cargo dependencies.

suppaftp = { version = "^6", features = ["async"] }

⚠️ If you want to enable both native-tls and async you must use the async-native-tls feature ⚠️ ⚠️ If you want to enable both rustls and async you must use the async-rustls feature ⚠️ ❗ If you want to link libssl statically, enable feature async-native-tls-vendored

Deprecated methods

If you want to enable deprecated methods of FTPS, please enable the deprecated feature in your cargo dependencies.

This feature enables these methods:

  • connect_secure_implicit(): used to connect via implicit FTPS


By default, the library will log if there is any log crate consumer on the user implementation. Logging can be if preferred, disabled via the no-log feature.

Examples 📚

use std::str;
use std::io::Cursor;
use suppaftp::FtpStream;

fn main() {
    // Create a connection to an FTP server and authenticate to it.
    let mut ftp_stream = FtpStream::connect("").unwrap();
    let _ = ftp_stream.login("username", "password").unwrap();

    // Get the current directory that the client will be reading from and writing to.
    println!("Current directory: {}", ftp_stream.pwd().unwrap());

    // Change into a new directory, relative to the one we are currently in.
    let _ = ftp_stream.cwd("test_data").unwrap();

    // Retrieve (GET) a file from the FTP server in the current working directory.
    let data = ftp_stream.retr_as_buffer("ftpext-charter.txt").unwrap();
    println!("Read file with contents\n{}\n", str::from_utf8(&data.into_inner()).unwrap());

    // Store (PUT) a file from the client to the current working directory of the server.
    let mut reader = Cursor::new("Hello from the Rust \"ftp\" crate!".as_bytes());
    let _ = ftp_stream.put_file("greeting.txt", &mut reader);
    println!("Successfully wrote greeting.txt");

    // Terminate the connection to the server.
    let _ = ftp_stream.quit();

Ftp with TLS (native-tls)

use suppaftp::{NativeTlsFtpStream, NativeTlsConnector};
use suppaftp::native_tls::{TlsConnector, TlsStream};

fn main() {
    let ftp_stream = NativeTlsFtpStream::connect("test.rebex.net:21").unwrap();
    // Switch to the secure mode
    let mut ftp_stream = ftp_stream.into_secure(NativeTlsConnector::from(TlsConnector::new().unwrap()), "test.rebex.net").unwrap();
    ftp_stream.login("demo", "password").unwrap();
    // Do other secret stuff

Ftp with TLS (rustls)

use std::str;
use std::io::Cursor;
use std::sync::Arc;
use suppaftp::{RustlsFtpStream, RustlsConnector};
use suppaftp::rustls::ClientConfig;

fn main() {
    let mut root_store = rustls::RootCertStore::empty();
    root_store.add_server_trust_anchors(webpki_roots::TLS_SERVER_ROOTS.0.iter().map(|ta| {
    let config = ClientConfig::builder()
    // Create a connection to an FTP server and authenticate to it.
    let config = Arc::new(rustls_config());
    let mut ftp_stream = RustlsFtpStream::connect("test.rebex.net:21")
        .into_secure(RustlsConnector::from(Arc::clone(&config)), "test.rebex.net")
    // Terminate the connection to the server.
    let _ = ftp_stream.quit();

Going Async

use suppaftp::{AsyncNativeTlsFtpStream, AsyncNativeTlsConnector};
use suppaftp::async_native_tls::{TlsConnector, TlsStream};
let ftp_stream = AsyncNativeTlsFtpStream::connect("test.rebex.net:21").await.unwrap();
// Switch to the secure mode
let mut ftp_stream = ftp_stream.into_secure(AsyncNativeTlsConnector::from(TlsConnector::new()), "test.rebex.net").await.unwrap();
ftp_stream.login("demo", "password").await.unwrap();
// Do other secret stuff

Built-in CLI client 🖥️

SuppaFTP comes also with a built-in command-line FTP client. This CLI application provides all the commands to interact with a remote FTP server and supports FTPS too. You can also use it as a reference to implement your project. You can find it in the cli/ directory.

You can simply install as any other rust application via Cargo:

cargo install suppaftp-cli
suppaftp --version
