---|---|
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.

CipherParameters | generateDerivedParameters(int keySize)
Generate a key parameter derived from the password, salt, and iteration
count we are currently initialised with.
|
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.

Parameters: digest the digest to be used as the source of derived keys.
Parameters: keySize the size of the key we want (in bits)
Returns: a KeyParameter object.
Throws: IllegalArgumentException if the key length larger than the base hash size.
Parameters: keySize the size of the key we want (in bits)
Returns: a KeyParameter object.
Throws: IllegalArgumentException if the key length larger than the base hash size.
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.
Throws: IllegalArgumentException if keySize + ivSize is larger than the base hash size.
