public final class TokenDSAPrivateKey
extends TokenPrivateKey
implements java.security.interfaces.DSAPrivateKey

This class represents an DSA private key key that is stored on a PKCS#11 device.

A cryptographic operation performed with this key occurs on the PKCS#11 device.

Constructor Detail

TokenDSAPrivateKey

public TokenDSAPrivateKey(PKCS11LibraryConnection pkcs11LC,
                  long session,
                  long objectHandle,
                  long slotID)

The constructor; creates a new TokenDSAPrivateKey instance.

Parameters:

pkcs11LC - the connection to the PKCS#11 library

session - the "read only" session

objectHandle - the handle to the private key on the PKCS#11 device

slotID - the slot ID under which the session was opened

Method Detail

getAlgorithm

public java.lang.String getAlgorithm()

Returns the standard algorithm name for this key, which is "DSA".

Specified by:

getAlgorithm in interface java.security.Key

Returns:

the standard name of the algorithm for this key

getParams

public java.security.interfaces.DSAParams getParams()

Returns the DSA-specific key parameters. These parameters are never secret.

Note: Because this key is stored on a PKCS#11 device, this call extracts the DSA parameters from the device.

Specified by:

getParams in interface java.security.interfaces.DSAKey

Returns:

the DSA-specific key parameters

getKeyLength

public int getKeyLength()

Return the length of the key in bits.

For example, for a DSA-1024 key, this API would return 1024.

Note: Because this key is stored on a PKCS#11 device, this call extracts the key length from the device.

Specified by:

getKeyLength in interface KeyWithLength

Returns:

the key length (in bits)

getX

public java.math.BigInteger getX()
                          throws java.lang.RuntimeException

Not supported.

Specified by:

getX in interface java.security.interfaces.DSAPrivateKey

Throws:

java.lang.RuntimeException - always thrown indicating that this API is not supported
