CDecrypt is a small application that decrypts/unpacks Wii U NUS Content.

Originally developed by crediar, this is an updated version made by VitaSmith with the following improvements:

• Has no external dependency whatsoever (no libOpenSSL or MSVC redistributable).
• Publicly built releases on AppVeyor with verifiable SHA-256.
• Can be compiled for Windows, Linux and macOS.
• Supports long paths on platforms that allow it.
• Supports international characters in path names.
• Does not need the executable to reside in the same directory as the content.
• Accepts either a file or directory (including non .tik/.tmd files).
• Accepts an optional target directory for extraction.
• Open Source (GPLv3+) with its source on GitHub.

User guide

Usage: cdecrypt <NUS file or directory> [<target directory or existing file>]

If only one parameter is specified, the content is extracted into the same directory where the NUS files reside. If an existing file is provided as the second parameter, it is ignored (to preserve compatibility with the previous versions of CDecrypt). If the second parameter is not an existing file, then it is used as the target directory to extract files in, with any intermediate directories created if needed.

Windows users can drag and drop a directory/file directly onto cdecrypt.exe.
