Abstract
A system is provided for secure client-side cryptographic key retrieval using cryptographic key splitting and wrapping. In particular, the system may generate an encryption key that may be wrapped using a wrapping key. The wrapping key may in turn be split into a plurality of parts that may be stored in a distributed manner on a client computing system and a cryptographic database. Furthermore, the wrapping key may be generated using an encryption algorithm that allows the wrapping key to be reconstituted with fewer than all of the plurality of parts. In this way, the system provides a secure way to restrict access to sensitive data to authorized parties.
