How it all began

We all use digital signatures whenever we log in to our bank account, show our e-passport or use our credit card at the shops. This would not be possible without Public Key Infrastructure (PKI) enabling us to communicate securely on an insecure public network, such as the Internet.

Developing PKI


In the eighties, there was a young boy named Tomas Gustavsson growing up in Handen, a suburb south of Stockholm. Tomas quickly developed an interest in computer code, fuelled by films like War Games. He tried a few times to hack into the accounts of his opponents in various computer games. His father bought him membership to the ABC Club, Sweden’s first computer asso­ciation. A lot of the discussions at the ABC Club were about IT security even back then.

In 1994, Tomas focused his attention on crypto­graphy. He was already a research assistant at the School of Computer Science at the Royal Institute of Technology (KTH) in Stockholm.

At this time, MIT released a standard for public key in­frastructure (PKI) with a central repository in Boston to create, store and distribute digital signatures. Soon, however, everyone in the cryptographic community realized that it was not viable to have only one certificate authority (CA).

The PrimeKey products


In 2001, Tomas and his team released the very first version of EJBCA. EJBCA is a PKI and CA software package. EJBCA became the most widely used PKI in the world today and is run by PrimeKey, the Swedish company which holds the copyright.

EJBCA Enterprise


In 2005, PrimeKey launched the very first version of SignServer. The software was originally developed to enable time-limited passports to be created in a fast and efficient way at airports. In this way, PrimeKey has helped forgetful travelers reach their destination for over a decade. SignServer has now grown to become advanced software for time stamping and code signing, digital documents, passport etc.


EJBCA and SignServer Appliance

In 2012, PrimeKey opened a subsidiary in Aachen, Germany. This was the birthplace of our hardware appliance products, which are groundbreaking solutions within PKI, Digital signing and security. With these appliances, you can now implement a PKI and Digital Signing solution in a fast, efficient and secure way. The use and development of our hardware appliance products has grown globally and now helps many companies install PKI in a smooth way.

PrimeKey SEE

At the RSA show in 2017, PrimeKey showed PrimeKey SEE (Secure Execution Environment) for the very first time. The appliance drew a lot of attention and demand has been high since day one. The SEE is history in the making, and you can read more about it here.
