EncapsulatedSecretExtractor

@Deprecated
public class CMCEKEMExtractor
extends java.lang.Object
implements EncapsulatedSecretExtractor

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.
