Constructor Detail

PKCS12ParametersGenerator

public PKCS12ParametersGenerator(Digest digest)
Construct a PKCS 12 Parameters generator. This constructor will accept MD5, SHA1, and RIPEMD160.
Parameters:
digest - the digest to be used as the source of derived keys.
Throws:
java.lang.IllegalArgumentException - if an unknown digest is passed in.
Method Detail

generateDerivedParameters

public CipherParameters generateDerivedParameters(int keySize)
Generate a key parameter derived from the password, salt, and iteration count we are currently initialised with.
Overrides:
generateDerivedParameters in class PBEParametersGenerator
Parameters:
keySize - the size of the key we want (in bits)
Returns:
a KeyParameter object.

generateDerivedParameters

public CipherParameters generateDerivedParameters(int keySize,
                                                  int ivSize)
Generate a key with initialisation vector parameter derived from the password, salt, and iteration count we are currently initialised with.
Overrides:
generateDerivedParameters in class PBEParametersGenerator
Parameters:
keySize - the size of the key we want (in bits)
ivSize - the size of the iv we want (in bits)
Returns:
a ParametersWithIV object.

generateDerivedMacParameters

public CipherParameters generateDerivedMacParameters(int keySize)
Generate a key parameter for use with a MAC derived from the password, salt, and iteration count we are currently initialised with.
Overrides:
generateDerivedMacParameters in class PBEParametersGenerator
Parameters:
keySize - the size of the key we want (in bits)
Returns:
a KeyParameter object.
