Abstract

A computer-implemented method for managing a life-cycle of at least in parts interdependent cryptographic keys is disclosed. Each of the cryptographic keys is signed and relates to a different one of artifacts. The method comprises creating a key manifest, wherein the key manifest comprises data about determined dependencies of the cryptographic keys at a point in time when one of the artifacts is built encrypting the key manifest with a manifest key, and upon a life-cycle change happening to one out of the group comprising one of the artifacts and one of the interdependent cryptographic keys in the key manifest of the one of the artifacts, the method comprises decrypting the key manifest and invoking an action to a related one out of the group comprising the one of the artifacts and at least one of the interdependent cryptographic keys in accordance with the key manifest.
