Class HybridKexBuilder.ClassicAgreement

java.lang.Object

zeroecho.sdk.builders.HybridKexBuilder.ClassicAgreement

Enclosing class:

HybridKexBuilder

public static final class HybridKexBuilder.ClassicAgreement
extends Object

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

Required inputs before building:

• algorithm(String) - classic algorithm id (for example "Xdh")
• privateKey(PrivateKey) - local classic private key
• peerPublic(PublicKey) - peer classic public key (out-of-band)

Optional inputs:

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

After configuring the classic leg, continue with pqcKem() to configure the PQC leg.

Since:

1.0

Method Details

algorithm

public HybridKexBuilder.ClassicAgreement algorithm(String algId)

Sets the classic agreement algorithm identifier.

Example for X25519 in this project: use "Xdh" with XdhSpec.X25519.

Parameters:

algId - algorithm id (must not be null)

Returns:

this configurator

Throws:

NullPointerException - if algId is null

Since:

1.0

spec

public HybridKexBuilder.ClassicAgreement 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

privateKey

public HybridKexBuilder.ClassicAgreement privateKey(PrivateKey key)

Sets the local private key for the classic leg.

Parameters:

key - private key (must not be null)

Returns:

this configurator

Throws:

NullPointerException - if key is null

Since:

1.0

peerPublic

public HybridKexBuilder.ClassicAgreement peerPublic(PublicKey key)

Sets the peer public key for the classic leg.

In HybridKexBuilder.ClassicMode.CLASSIC_AGREEMENT this key is assumed to be obtained out-of-band.

Parameters:

key - peer public key (must not be null)

Returns:

this configurator

Throws:

NullPointerException - if key is null

Since:

1.0

pqcKem

public HybridKexBuilder.PqcKem pqcKem()

Continues with PQC (KEM adapter) leg configuration.

Returns:

PQC configurator

Since:

1.0
