The present disclosure relates to deriving cryptographic keys for use in encrypting data based on a plaintext to be encrypted. An example method generally includes receiving, from a querying device, a request for a cryptographic key. The request generally includes data derived from a plaintext value to be encrypted and an indication of a type of the plaintext value to be encrypted. A cryptographic key is generated based, at least in part, on the derived data and the type of the plaintext value to be encrypted. The key deriver transmits the generated cryptographic key to the querying device.

Cryptographic key generation for logically sharded data stores

The present disclosure relates to processing data queries on a logically sharded data store. An example method generally includes receiving, from a client device, a query. The query generally comprises one or more data items and wherein at least one of the one or more data items comprises sensitive data. A query processor obtains, from a key management server, a cryptographic key to use to encrypt the record based on data derived from the one or more data items comprising sensitive data and a type of the sensitive data. The query processor generates an encrypted query based on the query and the obtained cryptographic key and executes the encrypted query against the logically sharded database.
