  2. Click on "Preferences" and then "Key Management".
  3. Click on "New Key" and follow the wizard to create a new GPG key pair.
  4. Choose a key size (e.g., 2048 bits) and a password for your private key.
  5. Save your public key to a file (e.g., my_public_key.asc).

Step 3: Configure Apple Mail

Step 4: Encrypt and decrypt emails

  1. Compose a new email in Apple Mail and select the recipient's email address.
  2. Click on the "Security" menu and select "Encrypt" (or press Cmd + Shift + E).
