Abstract

The present disclosure involves systems, software, and computer implemented methods for database integration with an external key management system. One example method includes receiving, by a database system, a key encryption key from an external key management system external to the database system that is used to encrypt a data encryption key used to encrypt database data. The data encryption key is obtained, by the database system, using the key encryption key. Encrypted database data is decrypted, by the database system and using the data encryption key, to obtain decrypted database data before performing an operation on the decrypted database data. The database system determines that the external key management system has performed an operation on the key encryption key. In response to determining that the external key management system has performed the operation on the key encryption key, the database system modifies operation of the database system.
