When you encrypt an email, you’re turning it into undecipherable ciphertext, whereas before it was plain text anybody could read. Encryption requires the use of a set of keys a public key and a private one . The recipient of your message will therefore require the private key that matches up with the public one or else they won’t be able to see what you’ve written!
