Constructor Detail

TokenRSAPrivateKey

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

The constructor; creates a new TokenRSAPrivateKey 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 "RSA".

Specified by:

getAlgorithm in interface java.security.Key

Returns:

the standard name of the algorithm for this key

getModulus

public java.math.BigInteger getModulus()

Returns the modulus.

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

Specified by:

getModulus in interface java.security.interfaces.RSAKey

Returns:

the modulus

getKeyLength

public int getKeyLength()

Return the length of the key in bits.

For example, an RSA-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)

Since:

7.2 SP2

getPrivateExponent

public java.math.BigInteger getPrivateExponent()

Not supported.

Specified by:

getPrivateExponent in interface java.security.interfaces.RSAPrivateKey

Throws:

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