public SymmetricKeyCreatorImpl(SymmetricKeyConfig config)
The constructor.- Parameters:
config- theSymmetricKeyConfig.

Method Detail
-
getAlgorithm
public String getAlgorithm()
- Specified by:
getAlgorithmin interfaceCryptoAlgorithm- Returns:
- the name of the underlying algorithm (e.g. "RSA", "NONEwithECDSA", etc.).
- See Also:
Key.getAlgorithm(),Signature.getAlgorithm(),MessageDigest.getAlgorithm(),SecureRandom.getAlgorithm(),Cipher.getAlgorithm()
-
getKeyLength
public int getKeyLength()
- Specified by:
getKeyLengthin interfaceKeyCreator- 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.
-
getKeyLength
public int getKeyLength(K key)
- Specified by:
getKeyLengthin interfaceSymmetricKeyCreator<K extends SecretKey>- Parameters:
key- theSecretKey.- Returns:
- the
key lengthof the given key.
-
createKey
public K createKey(String password)
- Specified by:
createKeyin interfaceSymmetricKeyCreator<K extends SecretKey>- Parameters:
password- the secret password.- Returns:
- the according
SecretKey.
-
createKey
public K createKey(byte[] key)
- Specified by:
createKeyin interfaceSymmetricKeyCreator<K extends SecretKey>- Parameters:
key- theSecretKeyasencoded data.- Returns:
- the deserialized
SecretKey.
