5	  This option provides support for a key type that holds the data for
6	  the asymmetric keys used for public key cryptographic operations such
7	  as encryption, decryption, signature generation and signature
8	  verification.

17	  This option provides support for asymmetric public key type handling.
18	  If signature generation and/or verification are to be used,
19	  appropriate hash algorithms (such as SHA-1) must be available.
20	  ENOPKG will be reported if the requisite algorithm is unavailable.

28	  This option provides support for parsing X.509 format blobs for key
29	  data and provides the ability to instantiate a crypto key from a
30	  public key packet found inside the certificate.

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

52	  This is intended for testing the PKCS#7 parser.
