The following text is a mini guide howto setup basic encrypted mysql
service. For more information search the MySQL and OpenSSL documentation.
Please not that OpenSSL is no longer enabled by default so you have to
rebuild the package yourself to get it work. See changelog.Debian enty
from 2004-12-02 for reasons.

0. Change to the mysql ssl directory
cd /etc/mysql/ssl/
#
# Setup your own Certification Authority
#
1. Create your own Certification Authority (CA) if you do not already have
one (e.g. for signing web or mail server certificates)
openssl req -x509 -new -days 9999 -newkey rsa:2048 -nodes \
-keyout ca-key.pem \
-out ca-cert.pem
#
# Create a server certificate
#
2a. Create the server certificate request
openssl req -new -newkey rsa:2048 -nodes \
-keyout server-key.pem \
-out server-csr.pem
2b. Sign this server request with the CA key to make a proper server certificate.
openssl x509 -req -days 9999 \
-CA ca-cert.pem -CAkey ca-key.pem -CAcreateserial -CAserial ca-srl.txt \
-in server-csr.pem \
-out server-cert.pem
2b. Adjust the following lines in /etc/mysql/my.cnf according to your needs:
[mysqld]
ssl-key=/etc/mysql/ssl/server-key.pem
ssl-cert=/etc/mysql/ssl/server-cert.pem
ssl-ca=/etc/mysql/ssl/ca-cert.pem
#
# Create the client certificates
#
3a. Create the client certificate request
openssl req -new -newkey rsa:2048 -nodes \
-keyout client-key.pem \
-out client-csr.pem
3b. Sign this server request with the CA key to make a proper server certificate.
openssl x509 -req -days 9999 \
-CA ca-cert.pem -CAkey ca-key.pem -CAcreateserial -CAserial ca-srl.txt \
-in client-csr.pem \
-out client-cert.pem
3c. Now move the client* files to the client machine and adjust the users ~/.my.cnf
or client hosts /etc/mysql/my.cnf:
[client]
ssl-key=/home/ch/client-key.pem
ssl-cert=/home/ch/client-cert.pem
#
# Now configure SSL login constrains.
#
4.a This allowes passwordless login if the cryptographic key, the client
("subject") uses, was certified by our CA ("issuer") to belong to
the user it claims to.
Don't be so lazy to just limit to a subject because without checking
the issuer - whom's key only we have - anybody could fake the subject
line rendering the whole thing nearly useless.
GRANT all
ON *.*
TO "my"
REQUIRE
subject "/C=DE/ST=NRW/L=Aachen/CN=Foo Bar/emailAddress=foobar@example.com" and
issuer "/C=DE/ST=NRW/L=Aachen/CN=Christian Hammers/emailAddress=ch@debian.org";
4.b Don't forget this one:
