encryption/decryption

hi all,
just to ask u all one thing regarding encryption/decryption.

i am migrating my database from mysql to pgSQL using a php script.
in mysql there is a table 'users' where a field 'password' is there of type varchar(30),
and is encrypted using AES algorithm, and when i check all the records in mysql it looks like:-

mysql> select * from USERS;
+----+----------+------------------+-------------------+------------+-------+
| id | name     | password         | password_modified | created_on | admin |
+----+----------+------------------+-------------------+------------+-------+
|  1 | Admin    | \uffff\uffff\u6fde\uffff\uffff
                        \uffff/|\uffff9A | Y                 | 2005-08-10 | Y     |
|  2 | sangeeta | \uffff\uffffX\uffff\uffff\u0215\u0635\uffffkg\uffffg\uffff | Y                 | 2005-08-13 | Y     |
