Class HybridKexBuilder.PqcKem

java.lang.Object
zeroecho.sdk.builders.HybridKexBuilder.PqcKem
Enclosing class:
HybridKexBuilder
public static final class HybridKexBuilder.PqcKem extends Object
Configurator for the PQC leg (KEM adapter).

Required inputs differ by role:

The PQC leg is always message-based: initiator produces a peer message (ciphertext) and responder consumes it. The hybrid context transports this payload as the PQC part of the hybrid message.

      Returns:
      this configurator
      Throws:
      NullPointerException - if algId is null
      Since:
      1.0

    • spec

      public HybridKexBuilder.PqcKem spec(ContextSpec spec)
      Sets the PQC context spec (algorithm parameters).
      Parameters:

      Throws:
      NullPointerException - if key is null
      Since:
