"Green bar" display with EV certificates (Extended Validation)

An EV SSL certificate installed on a machine triggers the green url bar in most browsers.

That green bar is a visual garantee that the transactions are secured on a website.

Green bar display on the most popular browsers:

In 2007, several surveys showed that the green bar display generated instant positive reactions for 75% of internet users, a 15% raise of the purchase intentions and a 15% decrease in the abandonment of the purchase process.

The EV SSL certificate is therefore a powerfull marketing tool that can boost your Ecommerce websites.

Additional licence purchase

Depending on your needs or your technical pool, you may need to buy additionnal certificates or licences.

A certificate's always sold to be installed on a unique machine (physical or virtual).The additionnal licence makes then possible to duplicate an existing certificate instead of buying a new one for each different machine you may use.

  • Physical machine:Electricaly connected machine
  • Virtual machine:In process machine

Several configuration can be encountered:

  • Active / Active
  • Active / Inactive
  • Back-up site
  • Several virtual machines on one physical machine

A digital certificate reissue

A new certificate can be reissued in substitution of an existing one with the same fields but a different pair of keys*.

That can be done in those situations:

  • A certificate loss after a hard disk failure
  • A software switching
  • The modification of the key sizes
  • The vulnerability of the privet key
  • The upgrating of the signature from MD5 to SHA1

*pair of keys : Item privet key / public key elements : if a new pair of keys is needed a new CSR has to be requested.
