I'm desparately trying to find an OS X app that can:
- generate PGP keys
- encrypt files or messages using someone's public key
- decrypt files or messages using my private key
However all the tools I've tried so far are either so incredibly user-unfriendly (and poorly documented) that I can't get them to work, or they tend to store all PGP keys somewhere on my system (I think 'keyring' is the correct term).
Or they even install all sorts of email plugins or addons or automatic encryption services. I don't want this. For privacy and security reasons, I don't want to leave any traces behind. And I'm not using this for email.
I just want to have someone's public key, and encrypt a random message with it, or receive an encrypted message from someone else and decrypt that.
Either a GUI or command line app would be fine (preferably something that I can install through brew or brew cask). Any suggestions?
