public class HPKEContextWithEncapsulation

extends HPKEContext

Sender-side HPKEContext that additionally carries the octet string produced by the KEM's encapsulation step.

Returned by / / / . The recipient never produces this subclass — the recipient already has the as input to the matching call.

getEncapsulation() returns a defensive copy of the encapsulated key for transmission to the recipient (typically prepended to the first ciphertext or carried in a wire-format wrapper such as MLS or OHTTP).
