Date: 2026-07-12

org.bouncycastle.pqc.crypto.cmce

## Class CMCEKeyParameters

- java.lang.Object
- - org.bouncycastle.crypto.params.AsymmetricKeyParameter
  - - org.bouncycastle.pqc.crypto.cmce.CMCEKeyParameters

- All Implemented Interfaces:
    CipherParameters
  Direct Known Subclasses:
    CMCEPrivateKeyParameters, CMCEPublicKeyParameters

  Deprecated.
  the standardised Classic McEliece KEM (ISO/IEC 18033-2:2006/Amd 2:2026) is now provided under org.bouncycastle.crypto and org.bouncycastle.jcajce (see org.bouncycastle.crypto.params.CMCEParameters and org.bouncycastle.jcajce.spec.CMCEParameterSpec). This is the legacy NIST round 3 (non-pc, incl. mceliece348864) implementation, retained for backwards compatibility.
