David Howells 206ce59a10 KEYS: Move the algorithm pointer array from x509 to public_key.c
Move the public-key algorithm pointer array from x509_public_key.c to
public_key.c as it isn't X.509 specific.

Note that to make this configure correctly, the public key part must be
dependent on the RSA module rather than the other way round.  This needs a
further patch to make use of the crypto module loading stuff rather than using
a fixed table.

menuconfig ASYMMETRIC_KEY_TYPE
tristate "Asymmetric (public-key cryptographic) key type"
depends on KEYS
help
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.

config ASYMMETRIC_PUBLIC_KEY_SUBTYPE
tristate "Asymmetric public-key crypto algorithm subtype"

select PUBLIC_KEY_ALGO_RSA
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.
config PUBLIC_KEY_ALGO_RSA
tristate "RSA public-key algorithm"
select MPILIB_EXTRA
help
This option enables support for the RSA algorithm (PKCS#1, RFC3447).

select ASN1
select OID_REGISTRY
help
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.
