This site is hosted through secure HTTP or HTTPS. This means that all traffic between you and this website is encrypted. However HTTPS has another feature, which is host identification; a way to make sure that the website you are talking to is indeed the website you think it is. For this purpose a secure website provides a certificate that has been granted by a certificate authority (CA). Since these certificates cost money, this site uses a certificate that was created by Orca Software itself rather than by a known CA. Your browser will complain about this. However, since this site does not host your bank details, it's quite safe to trust Orca Software as a CA. You can do this by installing this [/info/ca-cert.der CA Certificate] When using Chrome or IE on Windows, you will have to store this certificate in the "Trusted Root Certificates" store, other wise the browser will not trust it.
