└─> Cryptographic API

└─> Asymmetric (public-key cryptographic) key type

└─> Asymmetric public-key crypto algorithm subtype

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.
