Java AES Encryption

Java AES Encryption (256 Bit):

• First, look at http://stackoverflow.com/questions/15554296/simple-java-aes-encrypt-decrypt-example to understand a simple AES Encrypt and Decrypt
• Second, look at Apache Commons's http://commons.apache.org/proper/commons-codec/ for the ability to translate the raw binary string into a Base64/HEX value.
• Third, look at http://stackoverflow.com/questions/18362137/encryption-with-aes-256-java to understand how encryption works with Base64 conversion for DB storage
• Next, look at http://stackoverflow.com/questions/992019/java-256-bit-aes-password-based-encryption for detailed AES256 encryption/decryption
• I used the code from  "After reading through erickson's suggestions...". With 1 small comment:

• // I don't think this should happen, but just in case..
  if (tmp != null)
  fout.write (tmp);

• This is used for muti-part encryption. So make sure you don't just delete it or comment it out.
• Finally, look at Java 6 or Java 7 to understand how to overwrite the default 128 limit. Please read the disclaimer. I don't want anyone getting in trouble for US government export control rules.
