Method Detail

isValidKeyLength

public boolean isValidKeyLength(int length)

Description copied from class: RawKeyGenerator

Returns true iff length is a valid key length (in bytes) for this algorithm.

The default implementation returns true if length is between the minimum and maximum key lengths. Some algorithms will override this method to specify a more restricted set of values.

Specified by:

isValidKeyLength in interface ExtendedKeyGenerator

Overrides:

isValidKeyLength in class RawKeyGenerator
