LibSsh2 Native Builds

Pre-compiled native libssh2 libraries for multiple platforms. This repository automates the building of libssh2 for various operating systems and architectures.

Proudly vibecoded by Claude Code.

Supported Platforms

• Windows: x64
• Linux: x64, ARM64
• macOS: x64 (Intel), ARM64 (Apple Silicon)

Downloads

Download the latest pre-built libraries from the Releases page.

Each release includes:

• Individual platform-specific archives (e.g., libssh2-win-x64.zip, libssh2-linux-x64.zip)
• Combined archive with all platforms (libssh2-all-platforms.zip)

Build Information

All libraries are built with:

• OpenSSL 3.0.15 as the crypto backend
• Zlib compression enabled (Linux/macOS)
• Shared library configuration

Release descriptions include the exact libssh2 commit SHA used for building.

Building from Source

The build process is automated via GitHub Actions. To trigger a build:

1. Create a release tag:

   git tag release/1.0.0
   git push origin release/1.0.0

2. GitHub Actions will automatically:

   • Build libssh2 for all supported platforms
   • Create a GitHub release with all binaries

Manual Build

You can also trigger builds manually using the workflow dispatch feature in the Actions tab.
