Re: PKCS#11 Question

Steve,

What you say is correct, but even though the actual private key bits stored on the card aren't visible, Jay should still see private key entries that encapsulate a PKCS#11 object reference. It sounds like there might be a bug in our PKCS#11 driver.

The whole point behind any security token (like a smartcard) is that the private key never leaves that token, so it's not surprising that you don't see a key in the KeyChain. Certificates can be nailed to a post in the middle of town if you're so inclined, so they can be copied off the token and into the keychain, but not the private key.

Some smartcards generate the keypair on the card and only export the public key (from which the certificate is made). Other cards and tokens (e.g. USB) need the keypair to be installed on them first. But once all that has happened (and you've distributed the certificates to whoever needs them), PKCS#11 should handle the rest.

Im writing a java application that does authentication via Smart Cards
(PKCS#11) and need to get it functional on OSX. Using the SunPKCS11
provider with the library out in /usr/libexec/SmartCardServices/ pkcs11
it "half works". That is, it dosnt error, and can give some information
about the card and/or reader, but it seems to provide an empty KeyStore.

Ive looked around a little to see how to use the KeyChain via the
Apple.KeyChainStore provider instead, but I cant find any documentation
on it. Just using the basic usage examples Ive found:

ks = KeyStore.getInstance("KeychainStore","Apple");
ks.load(null,null);

I can see certificate entries for my smart card in the keystore, but no
key entries.

Ive found I can use keytool to test both cases easily:

keytool -keystore NONE -storetype PKCS11 -providerClass
sun.security.pkcs11.SunPKCS11 -providerArg pkcs11.config -list

The above lists PrivateKeyEntry's on Linux, and has 0 entries on Mac.

keytool -keystore NONE -storagetype KeychainStore -list - providerClass
com.apple.crypto.provider.Apple

The above lists trustedCertEntry's for the certs on the card, but no
PrivateKeyEntry.

Am I going about this wrong?

Jay
