public class DecryptorImpl
extends SessionImpl

The `DecryptorImpl` is the implementation used by the `Decryptor` service.
It uses RSA standard private key encryption for the implementation. The server should be in a consistent state before decryption services can be provided. If decryption services are requested of the `Decryptor` before the server is appropriately initialized, it throws an `InconsistentStateException`.

### decrypt

    public java.lang.String decrypt(java.lang.String dataToDecrypt)
                             throws InconsistentStateException

  Takes a byte string of data to decrypt and returns a string of plain text.
  The decryption process involves getting an instance of the KeyFactory and retrieving the private key from it. The encrypted data, which is really a base-64 encoded string, is then decoded to convert it to the byte sequence that the `Encryptor` returned as a result of the encryption process. This byte sequence is then passed on the decryption routine to get back the original text. A `SystemException` is thrown if the string being decrypted was encrypted using a public key that is not part of the key pair that the private key is a part of.

  Parameters:
    `dataToDecrypt` - The encrypted string that needs to be decrypted.
  Returns:
    s string of decrypted data.
  Throws:
    InconsistentStateException - if the server is not initialized with decryption password.
