Abstract
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.
