Interface KeyGenerator
- All Known Implementing Classes:
- PK11KeyGenerator
- public interface KeyGenerator
Generates symmetric keys for encryption and decryption.
initialize
public void initialize(int strength)
throws java.security.InvalidAlgorithmParameterException
- Parameters:
strength
- Key size in bits. Must be evenly divisible by 8.
initialize
public void initialize(java.security.spec.AlgorithmParameterSpec parameters)
throws java.security.InvalidAlgorithmParameterException
generate
public SymmetricKey generate()
throws java.lang.IllegalStateException,
TokenException,
java.io.CharConversionException
generatePBE_IV
public byte[] generatePBE_IV()
throws java.lang.IllegalStateException,
TokenException,
java.io.CharConversionException
- 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.
- Throws:
java.lang.IllegalStateException
- If the algorithm is not a PBE
algorithm, or the KeyGenerator has not been initialized with
an instance of PBEKeyGenParams
.TokenException
- If an error occurs on the CryptoToken while
generating the IV.
clone
public SymmetricKey clone(SymmetricKey key)
throws SymmetricKey.NotExtractableException,
java.security.InvalidKeyException,
TokenException
- Allows a SymmetricKey to be cloned on a different token.
- Throws:
SymmetricKey.NotExtractableException
- If the key material
cannot be extracted from the current token.java.security.InvalidKeyException
- If the owning token cannot process
the key to be cloned.
setCharToByteConverter
public void setCharToByteConverter(KeyGenerator.CharToByteConverter charToByte)
- Sets the character to byte converter for passwords. The default
conversion is UTF8 with no null termination.
