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.

18	  This option provides support for asymmetric public key type handling.
19	  If signature generation and/or verification are to be used,
20	  appropriate hash algorithms (such as SHA-1) must be available.

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