A a minimal, secure, and easy-to-use SFTP (SSH File Transfer Protocol) server written in Go. It has been designed to provide reliable file transfer capabilities over any reliable data stream. The server is configured to listen on port 55555 and supports basic file operations, including listing, uploading, and downloading files.
- SFTP Protocol Support: Implements a subset of the SFTP protocol for secure file transfers.
- Directory Whitelist: Configurable directory whitelist to restrict client access only to specified directories. The server does not allow access to folders at a higher level under any circumstances.
- File Upload & Download: Supports uploading and downloading files with conflict resolution. If an uploaded file already exists, the new file is renamed to prevent overwriting.
- Logging: Logs all actions performed by the server for auditing and debugging purposes.
The server configuration is handled via a JSON file that specifies the directories accessible by the server. This ensures a secure and controlled environment for file operations.
Security is a primary concern for Go-SFTP-Server. The server only supports SFTP for secure file transfers and follows secure coding practices to mitigate potential security risks.
The project provides a simple and intuitive command-line interface for managing the server. It's designed to be easy to use, even for those without a deep understanding of SFTP or Go.

Creating a secure SFTP server from scratch is a non-trivial task. Go-SFTP-Server is a demonstration project and should be thoroughly reviewed and tested before any production use.
