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

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

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