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.

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.

KEYS: Asymmetric public-key algorithm crypto key subtype Add a subtype for supporting asymmetric public-key encryption algorithms such as DSA (FIPS-186) and RSA (PKCS#1 / RFC1337). Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

config ASYMMETRIC_PUBLIC_KEY_SUBTYPE
tristate "Asymmetric public-key crypto algorithm subtype"
select MPILIB
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.

RSA: Implement signature verification algorithm [PKCS#1 / RFC3447] Implement RSA public key cryptography [PKCS#1 / RFC3447]. At this time, only the signature verification algorithm is supported. This uses the asymmetric public key subtype to hold its key data. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

This option enables support for the RSA algorithm (PKCS#1, RFC3447).
X.509: Add a crypto key parser for binary (DER) X.509 certificates Add a crypto key parser for binary (DER) encoded X.509 certificates. The certificate is parsed and, if possible, the signature is verified. An X.509 key can be added like this: # keyctl padd crypto bar @s </tmp/x509.cert 15768135 and displayed like this: # cat /proc/keys 00f09a47 I--Q--- 1 perm 39390000 0 0 asymmetri bar: X509.RSA e9fd6d08 [] Note that this only works with binary certificates. PEM encoded certificates are ignored by the parser. Note also that the X.509 key ID is not congruent with the PGP key ID, but for the moment, they will match. If a NULL or "" name is given to add_key(), then the parser will generate a key description from the CertificateSerialNumber and Name fields of the TBSCertificate: 00aefc4e I--Q--- 1 perm 39390000 0 0 asymmetri bfbc0cd76d050ea4:/C=GB/L=Cambridge/O=Red Hat/CN=kernel key: X509.RSA 0c688c7b [] Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

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.
