MySQL Encryption

[Alan M Dunsmuir]

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.

This is not really a PHP question, but there are a few ways to get to a
database hosted on a web server or separate dedicated database server.

For a web server, phpMyAdmin is a possibility. To do this safely over
the big bad internet, run it on https. (you can use a self-signed
certificate and give your own root certificate to the client if you do
not want to spend money on a web certificate).

Or, you can tunnel port 3306 (or whatever port MySQL is serving) to your
local PC using an SSH tunnel. PuTTY is a good SSH client. If you
restrict SSH access to just a few known IP addresses, you can build a
pretty secure maintenance facility. One advantage of tunneling is that
your client can use any database front-end program he likes. There are
even database front-end programs that have SSH tunneling support built-in.

Best regards.

Try comp.databases. mysql for your mysql questions. This is a PHP newsgroup.

No. It is actually a question about phpMyAdmin.

In that case, he should be asking in the phpMyAdmin support forums, not
here.

Sorry - tried to go back to edit and hit send instead...

If you're asking about phpMyAdmin, you should be asking the phpMyAdmin
support people. This is not a product support forum for anything which
just happens to be written in PHP.

I recommended comp.databases. mysql because export is a MySQL operation,
and you might be able to get some help there.

But this is not the correct forum to be asking your question.

You can use PHP, with it's mcrypt-crypto functions, see http://www.php.net
for details...There are a lot of open-source solutions for simple file
encryption ;)

OR

You can pay for other encryption-decryption software.

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.

<?php

if($argc <= 4 && is_file($argv[3]))
{
$input_file_add r = $argv[3];
$input = file_get_conten ts($input_file_ addr);
$key = $argv[1];
if($argv[2] == "-e")
{
$encrypted_data = @mcrypt_ecb(MCR YPT_RIJNDAEL_25 6, $key, $input,
MCRYPT_ENCRYPT) ;
//echo $encrypted_data . "\n";
$fp = fopen($input_fi le_addr,"w");
fwrite($fp,$enc rypted_data);
fclose($fp);
}
else if($argv[2] == "-d")
{
$encrypted_data = @mcrypt_ecb(MCR YPT_RIJNDAEL_25 6, $key, $input,
