Rebex.FileTransfer 8.0.9797

Rebex File Transfer - The C# universal file transfer library for .NET

Rebex File Transfer is a simple file transfer library that supports SFTP, FTP and FTPS (FTP over TLS) protocols through a single unified API. It is part of Rebex File Transfer Pack — a set of .NET libraries that includes dedicated Rebex.Sftp and Rebex.Ftp client libraries and a Rebex.FileServer SFTP and FTP server library.

The FileTransferClient class provides a protocol-agnostic API — write your file transfer code once and switch between SFTP, FTP or FTP/SSL by changing a single parameter.

20+ years of active development. Rebex File Transfer Pack has been continuously developed and maintained since 2003, with regular updates and new features.

Key features

• Protocol-agnostic API - single FileTransferClient class for SFTP, FTP and FTP/SSL; switch protocols with one parameter
• Connect and authenticate - SFTP, FTP, FTP/SSL (explicit and implicit); password, public key, Kerberos, NTLM
• SFTP client - full SFTP v3-v6 support (via Rebex.Sftp)
• FTP client - FTP and FTP/SSL with explicit and implicit TLS (via Rebex.Ftp)
• Cryptographic algorithms including PQC - ML-KEM, ML-DSA, Ed25519, ChaCha20/Poly1305, AES/GCM, ECDH, ECDSA, RSA, and more
• FIPS 140-3 compliant mode

Getting started

Connect to SFTP, FTP or FTP/SSL

var client = new FileTransferClient();

// connect to SFTP
client.Connect(hostname, FileTransferMode.Sftp);

// or connect to FTP
// client.Connect(hostname, FileTransferMode.Ftp);

// or connect to FTP/SSL (implicit)
// client.Connect(hostname, FileTransferMode.FtpSslImplicit);

// authenticate
client.Login(username, password);

// upload a file
client.PutFile(@"C:\MyData\file.txt", "file.txt");

// disconnect
client.Disconnect();

Authenticate with a private key (SFTP)

var client = new FileTransferClient();
client.Connect(hostname, FileTransferMode.Sftp);

// load the private key
SshPrivateKey privateKey = new SshPrivateKey("my_key.ppk", "key_password");

// log in
client.Login(username, privateKey);

Access underlying protocol object

var client = new FileTransferClient();
client.Connect(hostname, FileTransferMode.Ftp);

// access the inner Ftp object for protocol-specific operations
Ftp ftp = client.Inner as Ftp;
ftp.SendCommand("FEAT");

var response = ftp.ReadResponse();
Console.WriteLine(response.Raw);
