| 20 | This option provides support for asymmetric public key type handling. | |
| 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. | |
