Method Detail

clone

public SymmetricKey clone(SymmetricKey key)

Allows a SymmetricKey to be cloned on a different token.

Throws: SymmetricKey.NotExtractableException If the key material cannot be extracted from the current token. InvalidKeyException If the owning token cannot process the key to be cloned.

clone

public static SymmetricKey clone(SymmetricKey key, PK11Token token)

Allows a SymmetricKey to be cloned on a different token.

Parameters: key The key to clone. token The token on which to clone the key.

Throws: SymmetricKey.NotExtractableException If the key material cannot be extracted from the current token. InvalidKeyException If the owning token cannot process the key to be cloned.

generate

public SymmetricKey generate()

Generates the key. This is the public interface, the actual work is done by native methods.

Generates an Initialization Vector using a PBE algorithm. In order to call this method, the algorithm must be a PBE algorithm, and the KeyGenerator must have been initialized with an instance of PBEKeyGenParams.

Returns: The initialization vector derived from the password and salt using the PBE algorithm.
