Bun install script versioned URL checksum verification bun.sh/install bun-v1.3.13💡 Result:
The official Bun install script provided at https://bun.sh/install does not natively implement or prompt for checksum verification of the installation script itself when piped to shell [1][2]. The standard, recommended installation method—
curl -fsSL https://bun.sh/install | bash—executes the script directly from the remote URL without an integrated checksum check [3][4][5]. If you require security hardening, such as preventing man-in-the-middle attacks or ensuring the integrity of the downloaded script, you must perform the verification manually or via third-party tools. Manual Verification and Hardening Strategies: 1. Use Third-Party Verification Tools: Projects such as checksum.sh provide a wrapper to download, inspect, and verify scripts against a known checksum before piping them to a shell [6][7]. Note that you must independently obtain and trust the checksum for the specific script version you intend to execute [6][7]. 2. Download and Verify the Binary Directly: For production environments or CI/CD pipelines, it is standard security practice to bypass the install script entirely [8]. You can download the specific Bun release binary (e.g., bun-v1.3.13) directly from the official GitHub releases page [4]. The GitHub release for v1.3.13 includes a SHASUMS256.txt file, which allows you to cryptographically verify the downloaded zip archive before extracting it [4]. Example of verifying a direct download: BUN_VERSION="1.3.13" # Download the specific binary curl -LO "https://github.com/oven-sh/bun/releases/download/bun-v${BUN_VERSION}/bun-linux-x64.zip" # Verify using the checksum file provided in the release # (Ensure you verify the SHASUMS256.txt file itself from a trusted source) sha256sum -c SHASUMS256.txt --ignore-missing The official documentation does not provide a specific checksum for the install.sh script itself for each release, as the install script is generally maintained to fetch the latest or requested version dynamically [1][3]. Consequently, hardening efforts typically focus on version pinning and verifying the final binary assets provided in official GitHub releases rather than the install script itself [8].Citations:
