Abstract
An application server has a custodian application running thereon. The custodian application instantiates a cryptographic microservice. The cryptographic microservice application builds a white-box cryptographic enclave. The custodian application transmits a request for an authorization grant to an authentication computing system. In response, the authentication computing system returns the authorization grant. The custodian application transmits the authorization grant to the cryptographic microservice application. The cryptographic microservice application transmits the authorization grant to the authentication computing system and then receives a digitally signed certificate therefrom. The cryptographic microservice application receives a data encryption key from the custodian application. The cryptographic microservice application transmits a request to the authentication computing system. The request includes the digitally signed certificate, the data encryption key, and a request to decrypt the data encryption key. The cryptographic microservice application then receives the decrypted data encryption key from the authentication computing system.
