We provide an X.509-standard-compliant Java implementation of hybrid certificates, which enable the parallel usage of two independent cryptographic schemes within public key infrastructures and related applications.This enables a stepwise transition to post-quantum secure and hybrid algorithms without the risk of incompatibility problems.
