DmgWiz

DmgWiz lets you extract raw filesystem data from compressed and encrypted DMG files. It started as a dmg2img clone but has more features and is more secure due to the Rust programming language.

• Support for adc, zlib, bzip2 and lzfse compression
• Support for encrypted DMGs (AES-128 and AES-256)
• Runs on Windows, Linux, macOS

DmgWiz is both a CLI tool and a Rust crate so it can be integrated into other projects.
