#NullconBerlin2025 | Finding insecure cryptographic keys in DKIM, DNSSEC, OpenID Connect & elsewhere

This talk, presented by Hanno Böck, focuses on the identification of insecure cryptographic keys found in protocols such as DKIM, DNSSEC, and OpenID Connect. The speaker, who is a developer of the open-source tool badkeys, discusses various security vulnerabilities that he has discovered using this tool. The session emphasizes the importance of maintaining the confidentiality of private keys in public key cryptography and highlights the risks associated with known vulnerabilities across different technologies.
