Go bindings

Install github.com/benbenbang/libitofin/sdk/go@v0.45.0 with Go 1.27.1. The native archives and SHA-256 checksums are attached below for Linux amd64, Linux arm64, macOS amd64, and macOS arm64. cgo, a C compiler, and the matching native package are required. See the installation guide.

Windows amd64 native Go package (GNU/MinGW) is available with its SHA-256 checksum; use a matching MinGW cgo compiler.
