/**
 * Simple PGP encryptor between byte[]./*from ww w .  ja v a 2  s .  c om*/
 * 
 * @param clearData The test to be encrypted
 * @param passPhrase The pass phrase (key). This method assumes that the key is a simple pass
 *        phrase, and does not yet support RSA or more sophisiticated keying.
 * @param fileName File name. This is used in the Literal Data Packet (tag 11) which is really
 *        inly important if the data is to be related to a file to be recovered later. Because
 *        this routine does not know the source of the information, the caller can set something
 *        here for file name use that will be carried. If this routine is being used to encrypt
 *        SOAP MIME bodies, for example, use the file name from the MIME type, if applicable. Or
 *        anything else appropriate.
 * 
 * @param armor
 * 
 * @return encrypted data.
 * @exception IOException
 * @exception PGPException
 * @exception NoSuchProviderException
