I'm writing a Web application using PHP5 connecting to a MySQL database.
I've told the client's application administrator to look after back-ups
of the database by using the "Export" option in phpMyAdmin to
automatically copy the database contents (recorded as SQL statements) to
his desktop.
Is there some way I can include encryption in this download process?
(And equivalently, decryption should he need to restore the database
from a backed up copy?) He is running a Windows machine, so for him to
do this locally, as a separate step, would require the use of some
Windows encryption code, and would risk his leaving a open text version
of the database on his desktop for anybody to see.
Here is my simple mcrypt training script works on Linux PHP-5.2.6-26
a konsole program by the way.. You need libmcrypt-2.5.8 and PHP-5.2.6
compiled with mcrypt support.
