KEYS: Implement asymmetric key type Create a key type that can be used to represent an asymmetric key type for use in appropriate cryptographic operations, such as encryption, decryption, signature generation and signature verification. The key type is "asymmetric" and can provide access to a variety of cryptographic algorithms. Possibly, this would be better as "public_key" - but that has the disadvantage that "public key" is an overloaded term.

KEYS: Make the system trusted keyring depend on the asymmetric key type Make the system trusted keyring depend on the asymmetric key type as there's not a lot of point having it if you can't then load asymmetric keys onto it. This requires the ASYMMETRIC_KEY_TYPE to be made a bool, not a tristate, as the Kconfig language doesn't then correctly force ASYMMETRIC_KEY_TYPE to 'y' rather than 'm' if SYSTEM_TRUSTED_KEYRING is 'y'. Making SYSTEM_TRUSTED_KEYRING *select* ASYMMETRIC_KEY_TYPE instead doesn't work as the Kconfig interpreter then wrongly complains about dependency loops.

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.

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.
This is intended for testing the PKCS#7 parser.
