This paper presents the motivation for CrypLLM and describes its integration into CT2. We further discuss several e-learning scenarios in which the agent helps users understand, construct, and troubleshoot cryptographic workflows. Finally, we outline the system architecture and summarize current limitations as well as future directions.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/cryptography educatione-learning cryptographyartificial intelligencelarge language modelsArticle
