SSHBindpy Python Wrapper

SSHBindpy is a Python wrapper for the SSHBind Rust library. It provides a Pythonic interface to bind remote services—located behind multiple SSH jump hosts—to a local socket. The package exports a single context manager: SSHBinding.

Features

• Single Public API: Only the SSHBinding context manager is exposed. All internal functionality (i.e. the underlying bind and unbind functions) is hidden.
• Automatic Resource Management: The context manager binds a remote service upon entering the context and unbinds it upon exit.
• Secure Credential Handling: Uses SOPS-encrypted YAML files for secure and reproducible credential management.
• Rust-Powered Efficiency: Leverages the performance and reliability of the SSHBind Rust library.

System Requirements

Before using SSHBindpy, ensure your system meets the following prerequisites:

• OpenSSL: Provides necessary cryptographic functions.
• SOPS: Required for decrypting encrypted YAML credential files.
• Python: Version 3.8 or later.
• Rust Toolchain (Optional): Necessary for building the Rust extension (install via rustup).
• Nix/direnv (Optional): For reproducible development environments.

Installation

From PyPI

pip install sshbind

From Source Using Maturin

1. Clone the Repository:

   git clone https://github.com/Xyhlon/SSHBindpy.git
   cd SSHBindpy
   

2. Build the Package:

   With maturin:

   maturin build --release
   

   Or using Nix:

   nix build
   

3. Install the Built Wheel:

   Locate the wheel in the target/wheels/ directory and install it:

   pip install target/wheels/sshbind-*.whl
   

Usage

sshbind exports a single context manager: SSHBinding. Use it to bind a remote service to a local socket. The context manager automatically calls the underlying Rust functions to bind on entry and unbind on exit.

from sshbind import SSHBinding

with SSHBinding("127.0.0.1:8000", ["jump1:22", "jump2:22"], "remote.service:80", "secrets.yaml") as binding:
    # Use the bound service within this block.
    # The remote service is bound when entering the context,
    # and unbound automatically when exiting.
    pass

Development

Using Nix or direnv

For a reproducible development environment, you can use either Nix or direnv.

• With Nix:

  nix develop
  

  This command opens a shell with all necessary dependencies (Rust toolchain, OpenSSL, SOPS, etc.) preconfigured.

• With direnv: Create a .envrc file containing your environment variables and run:

  direnv allow
  

Without Nix

If you choose not to use Nix, ensure you have the following installed:

• Rust Toolchain: Install via rustup.
• OpenSSL: Install using your system’s package manager.
• SOPS: Install from your package manager or from source.
• Maturin: Install with pip:

  pip install maturin
  

Then build the package as described above.

Building and Publishing

Building the Package

• With Nix:

  nix build
  

• With Maturin:

  maturin build --release
  

Publishing the Package

To publish sshbind using maturin:

Publish Using Maturin:

maturin publish

Developer Dependencies

• Maturin: Build backend for compiling the Python extension.
• Rust Toolchain: For compiling the underlying Rust code.
• Nix/direnv (Optional): For reproducible development environments.
• Python 3.8+: The minimum supported Python version.
