European Parliament Crypto Tool

Crypto tool

Tools to improve the mechanism preventing double voting in European Parliament elections 

When is this solution for you? 

You work in a public administration of an EU Member State that needs to exchange electoral files in a secure way for the European Parliament elections.

What can we offer you? 

During the European Parliament elections, it is necessary to ensure a secure exchange of data of mobile voters and candidates and prevent double voting (Directive 93/109/EC - participation of EU citizens in EP elections). As a solution, the Commission has developed a crypto tool that all EU Member States can use to exchange the data. 

The tool generates credentials to exchange files in a secured way. It also provides statistics on the quality of the data exchanged.

A new version of the Crypto Tool was released in autumn 2018. This is the release that will be used during the European Parliament elections in May 2019.
