How do I use OpenSSL [closed]

I have a XAMPP localhost site running on my computer using 127.0.0.1 but I was wondering that because OpenSSL is included how do I use it for other purpose like for my emails.

Thanks in advance.

If you want to send encrypted e-mail what you need to do depends on what e-mail client you're using. If you're using gmail, for instance, there are browser plugins available which enable S/MIME support.

Alternately, you could use the smime command line tool to encrypt and decrypt the messages. You will need a public key from each recipient you want to send encrypted messages to.

If you just want to encrypt messages using a shared key (both you and the recipient know the password) as opposed to using public/private keys, you'd probably have an easier time using something like GPG
