For those who are interested in installing the release builds:
brew tap Picocrypt/picocrypt
brew install picocryptSince the app is not signed by an Apple Developer key, you will need to follow these instructions to unquarantine it.
brew help, man brew or check Homebrew's documentation.
Thank you to @vraravam for creating this cask!
If I release a new version of Picocrypt but seemed to forget updating this cask, feel free to create an issue in Picocrypt/Picocrypt with prefix Homebrew:.
