The eUCRITE API is a PQC library interface, that provides quantum-resistant cryptographic schemes in abstract manner. It provides not only PQC-based encryption, but also signature schemes. The end-user has the choice between three different security levels based on the strength and performance of the chosen algorithms. This abstraction aims at supporting crypt-agility and is expected to make using PQC-schemes easier. Collaborations on our cryptographic API, and a special update mechanism for said API are also under development.
