Class HPKEContextWithEncapsulation

java.lang.Object

org.bouncycastle.crypto.hpke.HPKEContext

org.bouncycastle.crypto.hpke.HPKEContextWithEncapsulation

public class HPKEContextWithEncapsulation
extends HPKEContext

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

Returned by HPKE.setupBaseS / SetupPSKS / setupAuthS / setupAuthPSKS. The recipient never produces this subclass — the recipient already has the enc as input to the matching setup*R 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).
