How to Associate your certificates with Apple Mail:

A signed message lets your recipients verify your identity as the sender; an encrypted message offers an even higher level of security. To send signed messages, you must have a personal certificate in your keychain. To send encrypted messages, the recipient’s certificate must be in your keychain.

  1. Choose File > New Message and, in the From pop-up menu, choose the account for which you have a personal certificate in your keychain.

    A Signed icon (containing a checkmark) in the lower-right side of the message header indicates the message will be signed when you send it. If you don’t see the icon, customize the header to include it.

  2. Address the message to recipients.
  • Some mailing lists reject signed messages because the signature is treated as an attachment. To send the message unsigned, click the Signed icon; an “x” replaces the checkmark.
  • An Encrypt (closed lock) icon appears next to the Signed icon if you have a personal certificate for every recipient in your keychain; the icon indicates the message will be encrypted when you send it.
  • If you don’t have a certificate for every recipient, you must cancel the message or send it unencrypted (click the Encrypt icon; an open lock icon replaces the closed lock icon).
