David Howells c08fed7371 KEYS: Implement encrypt, decrypt and sign for software asymmetric key [ver #2]
Implement the encrypt, decrypt and sign operations for the software
asymmetric key subtype.  This mostly involves offloading the call to the
crypto layer.

Note that the decrypt and sign operations require a private key to be
supplied.  Encrypt (and also verify) will work with either a public or a
private key.  A public key can be supplied with an X.509 certificate and a
private key can be supplied using a PKCS#8 blob:

	# j=`openssl pkcs8 -in ~/pkcs7/firmwarekey2.priv -topk8 -nocrypt -outform DER | keyctl padd asymmetric foo @s`
	# keyctl pkey_query $j - enc=pkcs1
	key_size=4096
	max_data_size=512
	max_sig_size=512
	max_enc_size=512
	max_dec_size=512
	encrypt=y
	decrypt=y
	sign=y
	verify=y
	# keyctl pkey_encrypt $j 0 data enc=pkcs1 >/tmp/enc
	# keyctl pkey_decrypt $j 0 /tmp/enc enc=pkcs1 >/tmp/dec
	# cmp data /tmp/dec
	# keyctl pkey_sign $j 0 data enc=pkcs1 hash=sha1 >/tmp/sig
	# keyctl pkey_verify $j 0 data /tmp/sig enc=pkcs1 hash=sha1
	#
