HPKEContextWithEncapsulation (Bouncy Castle Library 1.85 API Specification)

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).
