HashCheck is a Windows application that creates and verifies file checksums.

This project is compatible with:

• Visual Studio 2013
• Eclipse Luna CDT with MinGW (GCC 4.8.1)

Launch the executable to create a checksum file if it does not already exists.

Launch the executable to verify file integrity against a checksum file if it exists.

Hashing code found on the Internet is in the public domain:

MD5: Colin Plumb (1993) / John Walker (2003)

SHA1: Steve Reid (199?) / ... / Ralph Giles (2002)

FileStream code inspired by dotnet/corefx's Win32FileStream.cs. See FileStream.cpp for licensing information.

I wanted to have an executable having the least runtime dependencies possible.

MinGW's fstream can't open WCHAR filenames and I was not interested in changing fstream's implementation.

The coding style is inspired from Google C Style Guide.
