Method Details

encrypt

public byte[] encrypt(byte[] toEncrypt)
               throws Exception

Specified by:

encrypt in interface io.github.astrapi69.crypt.api.Encryptor<byte[],byte[]>

Specified by:

encrypt in class AbstractEncryptor<Cipher,SecretKey,String>

Throws:

Exception

newCipher

protected Cipher newCipher(SecretKey key,
 String algorithm,
 byte[] salt,
 int iterationCount,
 int operationMode)
                    throws NoSuchAlgorithmException,
InvalidKeySpecException,
NoSuchPaddingException,
InvalidKeyException,
InvalidAlgorithmParameterException,
UnsupportedEncodingException

Factory method for creating a new Cipher from the given parameters. This method is invoked in the constructor from the derived classes and can be overridden so users can provide their own version of a new Cipher from the given parameters.

Specified by:

newCipher in class AbstractCryptor<Cipher,SecretKey,String>

Parameters:

key - the key

algorithm - the algorithm

salt - the salt.

iterationCount - the iteration count

operationMode - the operation mode for the new cipher object

Returns:

the cipher

Throws:

NoSuchAlgorithmException - is thrown if instantiation of the SecretKeyFactory object fails.

InvalidKeySpecException - is thrown if generation of the SecretKey object fails.

NoSuchPaddingException - is thrown if instantiation of the cipher object fails.

InvalidKeyException - is thrown if initialization of the cipher object fails.

InvalidAlgorithmParameterException - is thrown if initialization of the cipher object fails.

UnsupportedEncodingException - is thrown if the named charset is not supported.
