Cannot wrap an EC key?

[Wei-Jun Wang]

Hi, PKCS #11 gurus,

    var sp = KeyPairGenerator.getInstance("EC", 
p).generateKeyPair().getPrivate();
    var k = KeyGenerator.getInstance("AES", p).generateKey();

    var cipher = Cipher.getInstance("AES/KW/PKCS5Padding", p);
    cipher.init(Cipher.WRAP_MODE, k);
    var wrapped = cipher.wrap(sp);
    cipher.init(Cipher.UNWRAP_MODE, k);
    cipher.unwrap(wrapped, "EC", Cipher.PRIVATE_KEY);

Here, p is SunPKCS11-NSS using sensitive config, and the last unwrap method 
reports an CKR_TEMPLATE_INCOMPLETE error. It runs fine with RSA.

Thanks,
Weijun
