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.
21 ENOPKG will be reported if the requisite algorithm is unavailable.

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.
