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
