SSL Certificate Error - SHA-256 EV

The purpose of a certificate is to encrypt the traffic between your computer and our servers, as well as authenticate that the website your browsing is in fact Helcim. If you've experienced a certificate error when browsing our website, please read the information below carefully:

  • You could have malware on your computer that is intercepting the connection.
  • You could be using an unsafe Internet connection.
  • Your computer could be in need of a software update.

We use an Extended Validation (EV) certificate provided by GeoTrust, with a SHA-256 signature algorithm. Having moved away from the older SHA1 to meet the latest PCI compliance requirements, there have been some reported issues with these latest certificates.

Mac OS x

While Mac OS X version 10.5+ can support SHA-256, there have been reports of bugs with 10.8 and 10.9 and the EV certificates (see links below). Users should patch their operating system with the latest version and updates.

Older Operating Systems

Windows XP (prior to SP3) is also unable to establish a connection with SHA-256 certificates. This is also the case for older operating systems and mobile devices:
