A utility that decrypts Wii U NUS content files.

This is a fork of https://code.google.com/p/cdecrypt intended for modders who want to explore or modify the content of the Wii U applications they own.

Unlike other clones, this version of cdecrypt has no external dependencies such as OpenSSL libraries and whatnot: A single executable file is all you need. It also supports international characters, does not need to reside in the same directory as the NUS content, and can be compiled for Linux.

cdecrypt <NUS file or directory>

The content is extracted into the same directory where the NUS files reside.
On Windows, you can also drag and drop a directory/file directly onto cdecrypt.exe.
