For those who are interested in installing the release builds:
brew tap Picocrypt/picocrypt
brew install picocrypt
Since 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 open a PR and mention me.
