SSL PFX to PEM and KEY

In case you have a wildcard PFX certificate and you need a PEM and your private KEY:

A *.pfx certificate is a PKCS#12 format and includes both the certificate and the private key.

1. Export the private key

openssl pkcs12 -in ABC.pfx -nocerts -out privatekey.pem -nodes

2. Export the certificate

openssl pkcs12 -in ABC.pfx -nokeys -out cert.pem

3.  Remove the passphrase from the private key

openssl rsa -in privatekey.pem -out server.key 

NMAP on OpenBSD

First you have to add the correct Path environment

export PKG_PATH=http://mirror.esc7.net/pub/OpenBSD/`uname -r`/packages/`machine -a`/

Then you can add the package:

pkg_add -v nmap
