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