Extract text from Wii U hash files (H3)
To convert H3 hash files to another format, you need CDecrypt or other Game software.
To convert other file formats to the "Console Data Integrity File" file type, you need software like CDecrypt or a similar tool.
The .H3 file is a proprietary data format used by the Nintendo Wii U console. It functions as a hash verification file, storing cryptographic SHA-1 hashes for encrypted game data chunks found in the accompanying APP files.
You typically encounter these files when downloading system updates or digital games via the Nintendo Update Server (NUS). Decryption and packaging tools like CDecrypt or Wii U USB Helper rely on these files to verify the integrity of the downloaded game content before decryption.
This format is highly restrictive and proprietary. It is not a playable game file by itself; it is entirely useless without the full suite of TMD, TIK, and APP files. Furthermore, because it contains raw binary data, standard text editors or web browsers cannot interpret it, making it incredibly frustrating to inspect manually.
Converting an .H3 file is rarely about changing its function, as doing so breaks its relationship with the game data. Instead, users usually want to extract the hash strings to TXT or HEX formats for debugging, verification, or homebrew development.
Because it is a closed, proprietary format tied to Nintendo's DRM architecture, standard online converters fail to process it. Often, only original console hardware or specific homebrew tools can properly read the data. Our system can inspect the file, and if our analysis detects a supported underlying format, viewing the raw text or conversion may still be possible.
Convert.Guru analyzes your H3 file, detects the exact format, and lets you read the text inside.
Users also converted 00000000, WUX, ZIP and H4 files.
If you want to convert H3 file to H4, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use CDecrypt or similar software from the "Cryptographic Hash Verification" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to H3, try CDecrypt or another comparable tool in the "Cryptographic Hash Verification" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our H3 converter.
