public class LunaKeyStore
extends java.security.KeyStoreSpi

This is the preferred means of managing Luna HSM access via the LunaProvider. This is the KeyStore engine class for storing objects on Luna hardware. The data in a Luna KeyStore corresponds to the objects in a hardware token. Like a JKS KeyStore, a Luna KeyStore must be loaded before being used. Unlike a JKS KeyStore, setting a key/certificate entry causes the key/certificate to be immediately written to the HSM as a token (permanent) object with the specified alias; the Luna provider does not wait until store() is called.

When no InputStream is specified, the KeyStore acts essentially as a front- end to the default HSM slot.

KeyStore ks = KeyStore.getInstance("Luna"); ks.load(null, "mypasswd".toCharArray());

The code above is the bare minimum necessary to get a Luna KeyStore up and running. This KeyStore is backed by the HSM partition that is at the currently specified default slot in LunaSlotManager. If no password is supplied in load, the user must log in via LunaSlotManager before using the keystore.

When the InputStream is backed by a file, the file should specify the slot to use in one of two formats. Using the string "tokenlabel:label" will attempt to open the KeyStore against the token with the provided label. Using "slot:<slotNum>" will attempt to open the KeyStore against the token at the provided slot. It is recommended that the token label be used, as the slot number of a given token may change but the label will not.

As well, the user type can be specified by adding a line with "usertype:<user type>" with possible values of CKU_CRYPTO_USER or CKU_CRYPTO_OFFICER.

Object Caching can be enabled for the LunaKeyStore by adding a line with "caching:true". If Caching is enabled the number of loading threads can be specified by adding a line with "loadingthreads:<number of threads>". If caching is enabled, adding a line with "cachingstrict:true" will prevent the LunaKeystore from accessing the HSM to search for the object if the object isn't found in the cache. If caching is enabled, adding a line with "clearcache:false" will prevent the object cache from being cleared when the LunaKeyStore is loaded. If caching is enabled, adding a line with "loadcache:false" will prevent the object cache from being loaded when the LunaKeyStore is loaded.

Using a file to back the InputStream in the load() method is optional. If there is no existing KeyStore file, a new KeyStore can be loaded by creating an InputStream backed by a String in one of the two formats above.

ByteArrayInputStream slot = new ByteArrayInputStream("slot:2".getBytes()); KeyStore ks = KeyStore.getInstance("Luna"); ks.load(slot, "mypasswd".toCharArray());

The code above will attempt to open a KeyStore on slot 2 with the partition password "mypasswd". Multiple KeyStores can be opened on the same slot, but they are not guaranteed to be thread-safe. External synchronization is recommended.

If an InputStream is provided that contains anything other than a string in one of the two formats above, the KeyStore will attempt to use the default slot.

The Luna KeyStore reads data from one PKCS11 slot. The slot number can be specified by having the InputStream contain a String that matches one of two forms:

• tokenlabel:<label> -- the labels of all available slots are matched against <label>. If a match is found, the KeyStore is set to read from the token at that slot.
• slot:<slotNumber> -- the KeyStore is set to read from the token at the given slot number.

The user type can be specified by adding the following on a separate line:

• usertype:<user type> -- the keystore will login to the HSM using the specifed <user type>. The possible values are CKU_CRYPTO_USER or CKU_CRYPTO_OFFICER

Object Caching for the LunaKeyStore can be enabled and configured by adding the following lines:

• caching:true -- enables caching for the LunaKeyStore which can help with performance.
• loadingthreads:<number of threads> -- number of threads used to load keys and certificates. The default is 1.
• cachingstrict:true -- when set if the object isn't found in the object cache, then the LunaKeyStore will consider there to be no object with the given alias and will return null or false and will not access the HSM to search for the object. This option can be used to optimize the performance in certain scenarios when there are many keys in the partition. This setting is disabled by default.
• clearcache:false -- prevents the object cache from being cleared when the LunaKeyStore is loaded. The default is true.
• loadcache:false -- prevents the object cache from being loaded when the LunaKeyStore is loaded. The default is true.

If the InputStream is null or contains data of any format other than the above, the KeyStore is set to read from the token at the current default slot number.

Specified by:

engineLoad in class java.security.KeyStoreSpi

Parameters:

inputStream - Determines the slot the keystore is loaded against as described above

password - Password for the slot. If no password is given, keystore operations will fail unless the user logs in to the slot directly using LunaSlotManager, or is already logged in

Throws:

java.io.IOException

java.security.NoSuchAlgorithmException

java.security.cert.CertificateException

engineStore

public void engineStore(java.io.OutputStream outputStream,
               char[] password)
                 throws java.io.IOException,
                        java.security.NoSuchAlgorithmException,
                        java.security.cert.CertificateException

Specified by:

engineStore in class java.security.KeyStoreSpi

Throws:

java.io.IOException

java.security.NoSuchAlgorithmException

java.security.cert.CertificateException

engineProbe

public boolean engineProbe(java.io.InputStream stream)
                    throws java.io.IOException

This is needed for JDK9+ as using keytool generates an exception without it when one is pointing to LunaProvider. The exception is innocuous but annoying and misleading.

Parameters:

stream - Input stream

Returns:

is KeyStore supported by this provider? yes, thus return true

Throws:

java.io.IOException - exception
