Class LunaSignature

java.lang.Object

java.security.SignatureSpi

com.safenetinc.luna.provider.signature.LunaSignature

Direct Known Subclasses:

LunaSignatureDSA, LunaSignatureRSA

public abstract class LunaSignature
extends SignatureSpi

A base class for all Luna provider signature engine classes.

Any key used to initialize a LunaSignature that was not created on the HSM will be imported into the current default HSM slot.

Constructor Detail

LunaSignature

public LunaSignature(long mechType)

Creates a new LunaSignature with the specified PKCS mechanism type. This is for use by the JCE internals only; normal access to objects of this class is through Signature.getInstance()

Parameters:

mechType - mechanism for signature

Method Detail

engineInitSign

protected void engineInitSign(PrivateKey privateKey,
                              SecureRandom random)
                       throws InvalidKeyException

Initializes this signature object with the specified private key for signing operations. The Luna provider supplies its own source of randomness, so the random parameter is ignored.

Overrides:

engineInitSign in class SignatureSpi

Parameters:

privateKey - the private key of the identity whose signature will be generated.

random - unused

Throws:

InvalidKeyException - if the key is improperly encoded, parameters are missing, and so on.

engineInitVerify

protected void engineInitVerify(PublicKey key)
                         throws InvalidKeyException

Specified by:

engineInitVerify in class SignatureSpi

Throws:

InvalidKeyException

engineInitSign

protected void engineInitSign(PrivateKey key)
                       throws InvalidKeyException
