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.

CLI Usage

dmgwiz [OPTIONS] <INPUT> [SUBCOMMAND]

OPTIONS:

info

dmgwiz <INPUT> info

decrypt

dmgwiz <INPUT> decrypt -o <output> -p <password>

extract

dmgwiz <INPUT> extract [-n <partition number>] -o <output>

Crate Usage

DmgWiz can also be used as a crate in other Rust projects. Please see the API Documentation and main.rs for examples how to use it.

Support for encrypted DMGs can be disabled to reduce the compilation time and amount of C code. To do this, add the default-features = false option in your Cargo.toml: 

[dependencies]
dmgwiz = {version = "0.2", default-features = false}
