Encrypt the given String.

Parameters:

string - The String to encrypt.

Returns:

The encrypted String.

Throws:

InvalidKeyException - the invalid key exception is thrown if initialization of the cypher object fails.

UnsupportedEncodingException - is thrown by get the byte array of the private key String object fails or if the named charset is not supported.

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

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

IllegalBlockSizeException - is thrown if Cipher.doFinal(byte[]) fails.

BadPaddingException - is thrown if Cipher.doFinal(byte[]) fails.

newAlgorithm

protected String newAlgorithm()

Description copied from class: AbstractCryptor

Factory method for creating a new algorithm that will be used with the cipher object.

Overrides:

newAlgorithm in class AbstractCryptor

Returns:

the string

newCipher

protected Cipher newCipher(String privateKey,
                           String algorithm,
                           byte[] salt,
                           int iterationCount,
                           int operationMode)

                           InvalidAlgorithmParameterException,
                           UnsupportedEncodingException

Description copied from class: AbstractCryptor

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.

Overrides:

newCipher in class AbstractCryptor

Parameters:

privateKey - the private 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 cypher object fails.

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

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