goploader

goploader is a lightweight project providing a Go-based server and command-line client to share files from the terminal or via curl-compatible tools. Files are streamed and encrypted server-side so the server never retains the decryption key.

Key Features

• Server and CLI client implemented in Go with a minimal footprint
• Server-side AES encryption performed while streaming uploads to disk
• Encryption key generated per upload and never persisted on the server
• Curl/httpie/wget compatible multipart upload API and stdin support for piping
• Simple metadata stored in an embedded key/value datastore (BoltDB)
• Designed for HTTPS deployments; commonly run behind Caddy with automatic certificates
• Small, scriptable client binary (gpldr) for terminal workflows
• Files are streamed to avoid buffering entire uploads in RAM

Use Cases

• Securely share files from the terminal or within shell scripts and CI pipelines
• Provide short-lived encrypted file links to collaborators without storing keys on server
• Build lightweight, privacy-oriented file drop services for teams or personal use

Limitations and Considerations

• Project is maintained as-is and some dependencies and approaches are dated; review before production use
• Uses an embedded BoltDB datastore which may require migration for heavy workloads or long-term maintenance
• No built-in user accounts, ACLs, or advanced access controls; link-based access only
• The default deployment relies on external HTTPS configuration (e.g., Caddy); secure deployment requires proper TLS setup
• The server may log uploader IPs depending on configuration; encryption keys are not retained

goploader is a pragmatic tool for terminal-first, privacy-focused file sharing, prioritizing streamed encryption and simplicity. It is suitable for personal or small-team use where short-lived encrypted links and scriptability are more important than advanced access control or enterprise features.
