MySQLDump Problem (no replies)

Hello I am Rohit Gupta,

I have developed a backup and restore utility with Mysqldump

command i am using to back up is
Mysqldump -uroot -pVvSnf4GF!A?Z@ -hlocalhost IDS -R
and command to restore database is
mysql -uroot -pVvSnf4GF!A?Z@ IDS < temp.sql

this is working fine but now i got a bug.

I have a table in database which is "user_master" this table is having a column named "login_password" its varchar(20), when i restore data everything works fine but this column values are not restored because those values are encrypted through "aes_encrypt" command.

Please suggest me the way to fix this problem.
