The German Country Signing Certificate Authority (CSCA)

This website contains information on the German CSCA operated by the Federal Office for Information Security (BSI).

The distinguished name of the CSCA is C=DE, O=bund, OU=bsi, CN=csca-germany.

CSCA Public Key Certificates

The CSCA uses two types of key pairs: a main key pair and a number of backup key pairs. The main key pair is used to issue Document Signer certificates. Backup key pairs are only used for disaster-recovery, i.e. in the unlikely case that the main key pair becomes unusable, the first backup key pair will become the new main key pair etc.

DER encoded certificates for the CSCA public keys can be found below. The information required to verify the authenticity of the following certificates is also available in authentic printed form upon request.

Certificate Rollover

The next rollover of the CSCA certificate is planned for 2019.
