SimpleBaseDecryptor

public SimpleBaseDecryptor(String privateKey)
                    throws InvalidKeyException,
                           NoSuchAlgorithmException,
                           InvalidKeySpecException,
                           NoSuchPaddingException,
                           InvalidAlgorithmParameterException,
                           UnsupportedEncodingException

Instantiates a new SimpleBaseDecryptor with the given private key.

Parameters:

privateKey - The private key.

Throws:

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

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

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

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

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

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

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