hactool is a C command-line tool for inspecting, decrypting, and extracting common Nintendo Switch file formats such as NCA, XCI, PFS0, RomFS, and HFS0 archives. It supports hash/signature verification, development and retail keys, and per-section extraction of Switch content archives.
Use cases
- extract romfs contents from a switch nca file
- decrypt nintendo content archives
- view info about an xci or nsp file
- verify hashes and signatures of switch files
- unpack exefs and pfs0 archives
- dump program permissions from npdm or kip1 to json
- decrypt with development keys for switch research
When to choose
- you need to inspect or extract Nintendo Switch file formats from the command line
- you want a scriptable tool for NCA, RomFS, ExeFS, or XCI decryption
- you are doing Switch reverse engineering or homebrew development
When to avoid
- you need a graphical interface for browsing Switch files
- you want to build or run Switch software rather than analyze its files
- you need support for other consoles' formats
