  21           If signature generation and/or verification are to be used,
  22           appropriate hash algorithms (such as SHA-1) must be available.
  23           ENOPKG will be reported if the requisite algorithm is unavailable.

  49           This option provides a type of key that can be loaded up from a
  50           PKCS#7 message - provided the message is signed by a trusted key.  If
  51           it is, the PKCS#7 wrapper is discarded and reading the key returns
  52           just the payload.  If it isn't, adding the key will fail with an
  53           error.
