Hash-o-Matic is a tool to compare and generate checksum for your files to verify the authenticity of them. In the background, the application was ported to the new QML type registration, we now support building Hash-o-Matic on Haiku and we now require released version of KDE Frameworks instead of pre-released version. You can find the package on download.kde.org and it has been signed with my GPG key.
