Abstract
An application server has a custodian application running thereon. The custodian application instantiates a cryptographic microservice. The custodian application transmits a request message to a centralized KMS requesting a data encryption key. In response, the centralized KMS returns the data encryption key. The custodian application transmits the authorization grant request to the centralized KMS and receives the authorization grant and encrypted data encryption key in return. The custodian application transmits the authorization grant and encrypted data encryption key to the cryptographic microservice application. The cryptographic microservice application transmits the authorization grant and encrypted data encryption key to the centralized KMS and receives the decrypted data encryption key in return.
