Class HybridKexBuilder.ClassicPairMessage

java.lang.Object

zeroecho.sdk.builders.HybridKexBuilder.ClassicPairMessage

Enclosing class:

HybridKexBuilder

public static final class HybridKexBuilder.ClassicPairMessage
extends Object

Configurator for the classic leg in HybridKexBuilder.ClassicMode.PAIR_MESSAGE mode.

Required inputs before building:

• algorithm(String) - classic algorithm id (for example "Xdh")
• keyPair(KeyPairKey) - local classic key pair wrapped as KeyPairKey

Optional inputs:

• spec(ContextSpec) - algorithm-specific context spec (for example XdhSpec.X25519)

In this mode, the classic leg contributes a public-key message (typically SPKI bytes) to the hybrid peer message. The peer public key is therefore learned from HybridKexContext.setPeerMessage(byte[]) rather than being supplied out-of-band.

Since:

1.0

Method Details

algorithm

public HybridKexBuilder.ClassicPairMessage algorithm(String algId)

Sets the classic agreement algorithm identifier.

Parameters:

algId - algorithm id (must not be null)

Returns:

this configurator

Throws:

NullPointerException - if algId is null

Since:

1.0

spec

public HybridKexBuilder.ClassicPairMessage spec(ContextSpec spec)

Sets the classic context spec (algorithm parameters).

Parameters:

spec - spec (may be null if the algorithm provides a default)

Returns:

this configurator

Since:

1.0

keyPair

public HybridKexBuilder.ClassicPairMessage keyPair(KeyPairKey keyPair)

Sets the local classic key pair.

The key pair is wrapped into KeyPairKey to match the PAIR_MESSAGE capability registered in core.

Parameters:

keyPair - key pair wrapper (must not be null)

Returns:

this configurator

Throws:

NullPointerException - if keyPair is null

Since:

1.0

pqcKem

public HybridKexBuilder.PqcKem pqcKem()

Continues with PQC (KEM adapter) leg configuration.

Returns:

PQC configurator

Since:

1.0
