FIXML interface new server certificates

Eurex Clearing Circular 091/21 FIXML interface new server certificates

1.   Introduction

With this circular, Eurex Clearing announces that new SSL/TLS certificates on the AMQP brokers used for the Eurex Clearing FIXML Interface in simulation and production environment will be installed. The new certificates will replace the existing certificates which are approaching their expiration date. 

Please note that the duration of the certificates is established by third party regulation and it is consistent across all certification authorities.

The new certificates will be activated as follows:

  • In simulation: 29 October 2021
  • In production: 6 November 2021

2.   Required action

The new public keys will be available for download on 18 October 2021 for simulation and 25 October 2021 for production on the Eurex Clearing website www.eurex.com/ec-en under the following link:

Support > Initiatives & Releases > C7 Releases > C7 Release 8.0 > System Documentation > Interfaces

Clearing Members are advised to download the new public keys from the Eurex website and install them in their client applications prior to the activation dates. If required, Clearing Members can test connectivity in the production environment. The connection test will be conducted on Saturday, 6 November 2021, between 12:00 and 15:00 CET.

3.   Details of the initiative

The certificates are signed by the DigiCert certification authority (CA). The root and intermediate certificates of the CA are available for download on their official website www.digicert.com.

The public keys of the AMQP brokers or the public keys of the CA must be installed first on the client’s side for the client application to accept the server certificates. Most AMQP clients can work with multiple certificates at the same time, therefore it is possible to upload the public keys in advance. Once the new certificate is installed on Eurex side, client’s application will automatically switch to the new certificate.

After activation dates, the connection will only work with the new public keys. This change does not affect certificates that were created by the Clearing Members and uploaded in the Clearing Member Portal.

More details about the SSL/TLS configuration of different AMQP libraries can be found in the Eurex Clearing Messaging Interfaces documentation: “Eurex Clearing Messaging Interfaces - Connectivity B: AMQP Programming Guide, V. 2.1” on the Eurex Clearing website www.eurex.com/ec-en/ under the following link:
