I have my email client configured to use the GNU Privacy Guard to implement OpenPGP encryption, should anyone wish to send me secure communications.
If you wish, and are able to use it, you can download my public OpenPGP Key.
Because I resent paying money to protection rackets I am not willing to pay Certificate Issuers for my servers security certificates.
I don't see why I should have to pay one of a small coterie of companys that browser publishers (i.e Microsoft) have deemed worthy of money. It isn't as if they actually do anything for their money. If I paid Thawte hundreds (even thousands) of dollars for a few milliseconds of CPU time to encrypt a key for me would that service include a thorough investigation of my identitiy and ethics? No, but that's what their service implies has occurred for visitors to my now Authorised site.
Security between a browser and a website is nothing more than a degree of encryption (hopefully defeating attempts to eavesdrop or manipulate communications in the middle of their trip), whether or not there's anything else 'secure' about the transaction is just a matter of personal trust.
So I've used OpenSSL to create my own root authority certificate, and server certificates derived from that.
If you would like to install my root certificate (which you shouldn't if you don't know and trust me explicitly with your security), and thereby have your browser trust other certificates issued by me click here to import puna.net.nz's root certificate.
Hopefully your browser will ask you if you wish to install and trust the certificate. If you agree click on any relevant or "Install Certificate" options and accept the defaults where you aren't certain of your options.
If your browser does not recognise that it should be installing a certificate then save the certificate to a file and manually import it by which ever process your browser requires.
You can happily use any secured connection with puna.net.nz without installing and trusting my root certificate. All browsers will let you use secure connections by saying that you will briefly trust an unauthorised certificate for the current session.
If you do install my root certificate then you'll never be bothered again by such questions, but do so only if you're certain you trust me - and that includes trusting me not to make some silly mistake or accidentally leave keys lying around.
