CryFS is distributed via Homebrew. Just do
brew cask install osxfuse
brew install cryfs
Windows (experimental)
----------------------
CryFS has experimental Windows support since the 0.10 release series. To install it, do:
1. Install [DokanY](https://github.com/dokan-dev/dokany/releases)
2. Install [Microsoft Visual C++ Redistributable for Visual Studio 2017](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads)
3. Install [CryFS](https://www.cryfs.org/#download)
