Abstract: Systems and methods for creating and making use of a cryptographic inventory are provided. According to one embodiment, cryptographic resources are discovered within one or more of a private datacenter, a colocation facility, and a public cloud. The cryptographic resources include assets and respective cryptographic material used by the assets. Respective relationships among the cryptographic resources are determined or inferred. Based on the cryptographic resources and the respective relationships, a cryptographic inventory is created or updated in a form of a semantic network that may be used to facilitate cryptoperiod reduction by enabling automated performance of a cryptographic action involving multiple of the cryptographic resources in which nodes of the semantic network represent the cryptographic resources and edges of the semantic network represent the respective relationships.
