Class CMCEParameters

java.lang.Object
org.bouncycastle.crypto.params.CMCEParameters
All Implemented Interfaces:
CipherParameters, KEMParameters
public class CMCEParameters extends Object implements KEMParameters
Parameter sets for the Classic McEliece KEM as standardised in ISO/IEC 18033-2:2006/Amd 2:2026, Clause 13.

Four parameter sets are provided for each of the four standardised code sizes (460896, 6688128, 6960119 and 8192128): a base set, a semi-systematic key-generation variant ("f"), a plaintext-confirmation variant ("pc"), and a combined variant ("pcf"). All sixteen sets use GF(2^13) and produce a 256-bit (32-byte) session key. The non-standardised mceliece348864 size is not provided here; it remains available (deprecated) under org.bouncycastle.pqc.crypto.cmce.
