   5  * Encrypt configuration is defined in groups which allows you to easily switch
   6  * between different encryption settings for different uses.
   7  * Note: all groups inherit and overwrite the default group.
   8  *
   9  * Group Options:
  10  *  key    - Encryption key used to do encryption and decryption. The default option
  11  *           should never be used for a production website.
  12  *
  13  *           For best security, your encryption key should be at least 16 characters
  14  *           long and contain letters, numbers, and symbols.
  15  *           @note Do not use a hash as your key. This significantly lowers encryption entropy.
  16  *
  17  *  mode   - MCrypt encryption mode. By default, MCRYPT_MODE_NOFB is used. This mode
  18  *           offers initialization vector support, is suited to short strings, and
  19  *           produces the shortest encrypted output.
  20  *           @see http://php.net/mcrypt
  21  *
  22  *  cipher - MCrypt encryption cipher. By default, the MCRYPT_RIJNDAEL_128 cipher is used.
  23  *           This is also known as 128-bit AES.
  24  *           @see http://php.net/mcrypt
