Mike Easter tried to help you already. Did you not understand what he
presented ?
Yahoo free means Yahoo webmail which doesn't support the signing and
encrypting of email. You need an email client that supports PKI and an
email account providing POP/IMAP/SMTP. MS Outlook, Outlook Express and
Winmail come to mind.
