  26         The functions provided in SecCertificate.h implement and manage a
  27     particular type of keychain item that represents a X.509 public key
  28     certificate. You can store a certificate in a keychain, but a
  29     certificate can also be a transient object.
  30
  31         You can use a certificate as a keychain item in most functions.
