Implement PKCS#8 RSA Private Key format [RFC 5208] parser for the asymmetric key type. For the moment, this will only support unencrypted DER blobs. PEM and decryption can be added later. PKCS#8 keys can be loaded like this: openssl pkcs8 -in private_key.pem -topk8 -nocrypt -outform DER | \ keyctl padd asymmetric foo @s Signed-off-by: David Howells <dhowells@redhat.com> Tested-by: Marcel Holtmann <marcel@holtmann.org> Reviewed-by: Marcel Holtmann <marcel@holtmann.org> Reviewed-by: Denis Kenzior <denkenz@gmail.com> Tested-by: Denis Kenzior <denkenz@gmail.com> Signed-off-by: James Morris <james.morris@microsoft.com>

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 provides a type of key that can be loaded up from a
|
|
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.
