NAME
       Jifty::DBI::Filter::SaltHash - salts and hashes a value before storing it

DESCRIPTION
       This filter will generate a random 4-byte salt, and then MD5 the given value with the salt appended to the value. It will store the hash
       and the salt in the database, and return a data structure that contains both on decode. The salt and hash are stored in hexadecimal in the
       database, so that you can put them in a text field.

       This filter is intended for storing passwords in a database.

   encode
       Generate a random 4-byte salt, MD5 the value with the salt (encoded to hexadecimal) appended to it, and store both in the database.

   generate_salt
       Return a random 4-byte salt value, encoded as an 8-character hex string.

   decode
       Return an arrayref of (hash, salt), both as hex strings.

       To test whether a provided value is the same one originally encoded, use

	   $hash eq md5_hex($value . $salt);
