I've just reposted this.  The interface you're using should be the same, I
think, but the details underneath have changed.

Also, you can now supply private keys to the kernel if they're PKCS#8 encoded
and keyctls are supplied that do encryption, decryption, signing and
verifying, e.g.:

	j=`openssl pkcs8 -in ~/pkcs7/firmwarekey2.priv -topk8 -nocrypt -outform DER | \
	    keyctl padd asymmetric foo @s`
	echo -n abcdefghijklmnopqrst >/tmp/data
	keyctl pkey_encrypt $j 0 /tmp/data enc=pkcs1 >/tmp/enc
	keyctl pkey_decrypt $j 0 /tmp/enc enc=pkcs1 >/tmp/dec
	cmp /tmp/data /tmp/dec
	keyctl pkey_sign $j 0 /tmp/data enc=pkcs1 hash=sha1 >/tmp/sig
	keyctl pkey_verify $j 0 /tmp/data /tmp/sig enc=pkcs1 hash=sha1
