Introduce the internal/archive package with a generic Extractor interface for extracting archive contents to a destination directory. Includes two implementations: - ZipExtractor: handles zip-based archives (.zip, .jar, .war, etc.) - TarExtractor: handles tar-based archives (.tar, .tar.gz, .tar.bz2, etc.) Both extractors enforce configurable safety limits and protect against common malicious-archive vectors: - Per-archive extraction size limit - Per-archive file count limit - Zip-slip path traversal prevention via existing SafeJoin - Symlink entries are written as real symlinks only when their target resolves inside destDir; symlinks pointing outside are dropped to avoid escape via symlink-then-write - Non-regular non-symlink entries (devices, fifos, sockets) are skipped because their contents can't safely round-trip to disk Also provides FindExtractor for auto-detecting archive format, and IsExcludedExtension for filtering by extension.

Syft
A CLI tool and Go library for generating a Software Bill of Materials (SBOM) from container images and filesystems. Exceptional for vulnerability detection when used with a scanner like Grype.
Features
- Generates SBOMs for container images, filesystems, archives (see the docs for a full list of supported scan targets)
- Supports dozens of packaging ecosystems (e.g. Alpine (apk), Debian (dpkg), RPM, Go, Python, Java, JavaScript, Ruby, Rust, PHP, .NET, and many more)
- Supports OCI, Docker, Singularity, and more image formats
- Works seamlessly with Grype for vulnerability scanning
- Multiple output formats (CycloneDX, SPDX, Syft JSON, and more) including the ability to convert between SBOM formats
- Create signed SBOM attestations using the in-toto specification

Installation
The quickest way to get up and going:
curl -sSfL https://get.anchore.io/syft | sudo sh -s -- -b /usr/local/bin
Tip
See Installation docs for more ways to get Syft, including Homebrew, Docker, Scoop, Chocolatey, Nix, and more!
The basics
See the packages within a container image or directory:
# container image
syft alpine:latest
# directory
syft ./my-project
To get an SBOM, specify one or more output formats:
# SBOM to stdout
syft <image> -o cyclonedx-json
# Multiple SBOMs to files
syft <image> -o spdx-json=./spdx.json -o cyclonedx-json=./cdx.json
