public interface KeyCreator
extends CryptoAlgorithm

Abstract interface for dealing with cryptographic keys. As symmetric and asymmetric key creation are so different there is no common method here. This might change in the future.

Since:

1.0.0

Method Detail

getKeyLength

int getKeyLength()

Returns:

the length of the key in bits. The bigger the key length the stronger and more secure the encryption but also the more computation power is required. Reasonable values depend on the algorithm: A recent value for RSA is 4096 bits while for PBKDF2 256 may be sufficient.
