The MinIO server runs a key-derivation algorithm to generate the KEK using a pseudo-random function ([PRF](#prf)):
`KEK := PRF(EK, IV, context_values)` where:

- [EK](#ek): is the external key. In case of SSE-C this is the client-provided key. In case of SSE-S3  this is secret key generated by the KMS. For further details see [SSE-C](#Server-Side-Encryption-with-client-provided-Keys) or [SSE-S3](#Server-Side-Encryption-with-a-KMS).
