KEYS: Implement PKCS#8 RSA Private Key parser [ver #2]
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>
