How to import a private key and certificate into a java keystore

noreply@blogger.com (DJ) — Mon, 19 Oct 2009 19:13:00 +0000

Convert to PEM format via openssl :

openssl pkcs8 -topk8 -nocrypt -in key.pem -inform PEM -out key.der -outform DER
openssl x509 -in cert.pem -inform PEM -out cert.der -outform DER

Import private key and cert via ImportKey class

Import the keystore generated above into your existing keystore :

keytool -v -importkeystore -srckeystore "C:\keystore.ImportKey" -destkeystore "C:\.keystore"

(optionally you can specify the alias via –srcalias and –destalias, note that an alias is unique within the keystore)

Back from a long break

noreply@blogger.com (DJ) — Mon, 19 Oct 2009 19:07:00 +0000

As you can, i will start to post again, hopefully on a regular basis :-) Found a nice tool to edit my blogs on my mac, which normally should help to increase the number of posts here.

Additionally i also moved hosts, previous this blog was located on dreamhost, but the speed was really become to slow for me to decently create quick posts. I therefore decided to move to blogger and was able to find a port of on my favorite themes :)

How to configure a user on SUN Solaris 10

noreply@blogger.com (DJ) — Wed, 04 Feb 2009 21:59:00 +0000

edit /etc/passwd and update the shell, for example, i want to configure bash for root
root:x:0:0:Super-User:/:/usr/bin/bash

log out and log in again to verify.

within your home folder, also specified in /etc/passwd, above example sets / as the home folder for root, create a .profile file with the following content

export TERM=vt100
export PS1="\$USER@$HOSTNAME:\w> \[\e[0m\]"

this will set your terminal to vt100, which allows for easy editing and does some formatting on your prompt :-)
check http://en.wikipedia.org/wiki/PS1 for more info!
