Embodiments are directed to managing cryptographic keys in a multi-tenant cloud based system. Embodiments receive from a client a request for a wrapped data encryption key ('DEK'). Embodiments generate a random key and fetch encryption context that corresponds to the client. Embodiments generate the wrapped DEK including the random key and the encryption context encoded in the wrapped DEK. Embodiments then return the wrapped DEK to the client.

Cloud based key management

Key generation and roll over is provided for a cloud based identity management system. A key set is generated that includes a previous key and expiration time, a current key and expiration time, and a next key and expiration time, and stores the key set in a database table and a memory cache associated with the database table. At the current key expiration time, the key set is rolled over, including retrieving the key set from the database table, updating the previous key and expiration time with the current key and expiration time, updating the current key and expiration time with the next key and expiration time, generating a new key and expiration time, updating the next key and expiration time with the new key and expiration time, and updating the key set in the database table and the memory cache.

Key generation and rollover

A key store microservice is provided for a cloud based identity management system. The key store microservice receives, over a network, a request from a client application to retrieve a key, the request including a tenancy identifier, and determines whether the key is present in a tenant specific memory cache associated with the tenancy identifier. When the key is determined to be present in the tenant specific memory cache, the key store microservice retrieves the key from the tenant specific memory cache, retrieves a decryption key from a key wallet, decrypts the key retrieved from the tenant specific memory cache using the decryption key retrieved from the key wallet, and sends, over the network, the key to the client.
