I want to encrypt a file then email it. The recipient needs to decrypt it. Needs to be free.
I'm looking for an encryption application that runs on Windows 10 and macOS 10.10 at a minimum. Would be nice if the app run on android, ios, macOS and Windows. All I want is to have the application: Ask one question, provide file, then encrypt file.
Actually, it doesn't have to be the same app, but multiple apps that encrypt and decrypt in the same format.
Does Windows have encryption? Could I find an app that mimics the windows encryption?
What I don't want is for the app to ask a lot of questions like what type of encryption I want,how to save the output file, save a bunch of files on my drive, no command line stuff, easy to hack file, etc.
