Installation

# Using pipx (recommended for CLI tools)
pipx install bb2gh

# Using pip
pip install bb2gh

PyPI and GitHub Releases are the supported public release channels.

The private repository builds the hardened bundle, and the public repository owns the visible GitHub Release and PyPI publication for that exact wheel.

If you need the exact published wheel, download it from GitHub Releases and verify it with the release checksums:

# Linux
sha256sum -c SHA256SUMS

# macOS
shasum -a 256 -c SHA256SUMS

On Windows PowerShell, use Get-FileHash for the downloaded wheel and compare it with the matching entry in SHA256SUMS.

Source-install from the public repository is unsupported in the hardened public release path. Homebrew is paused until a hardened formula exists.
