Life in Technicolor.
This second sticky note describes how to (1) convert a P12 file to PEM, and how to (2) merge a PEM and a CRT file to P12.
# covert openssl pkcs12 -nocerts -in key_in.p12 -out key.pem # merge openssl pkcs12 -export -inkey key.pem -in pki.crt -out key_out.p12

This post is just a sticky note, because for testing purposes I have to create a self-signed certificate from time to time.
openssl genrsa -des3 -out server.key 1024 openssl req -new -key server.key -out server.csr cp server.key server.key.org openssl rsa -in server.key.org -out server.key openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Yeah! Yesterday I finally updated my blog to WordPress version 2.8. And it was harder as expected: The update of the system finished successfully, but unfortunately the theme (K2) and most of the plugins stopped working 
Fixing the theme issue was easy. If you also use the famous K2 theme, just download the latest nightly release. Yep, I don’t really trust nightly builds (even if it’s a release candidate), but it worked surprisingly well. Give it a try! Then, while I tried to update the corresponding plugins, I found out that it’s possible to omit the following plugins just by modifying the configuration:
Revision Control: I don’t wanna use revisions of posts and pages, because I’m already happy with the nice auto-save feature. Recently, I applied the Revision Control plugin, but there’s an easier way to disable revisions. Just add the following line to your wp-config.php file (before the wp-settings.php include).
define('WP_POST_REVISIONS', false);
Admin SSL: I wanna secure the entire admin area of my blog, e.g. passwords must not be sent in plain text! A short time ago, I applied the Admin SSL plugin, but again there’s an easier way to enable SSL. Just add the following two lines to your wp-config.php file (before the wp-settings.php include).
define('FORCE_SSL_LOGIN', true); define('FORCE_SSL_ADMIN', true);
I must admit that I was afraid to do the WordPress update (“Never stop a running system.”). But now it’s good to see how one can simply reduce WordPress’ plugin dependencies.
