org.bouncycastle.jcajce.provider.asymmetric.mldsa
Class HashSignatureSpi.MLDSAExtHash

java.lang.Object
  java.security.SignatureSpi
      org.bouncycastle.jcajce.provider.asymmetric.util.BaseDeterministicOrRandomSignature
          org.bouncycastle.jcajce.provider.asymmetric.mldsa.HashSignatureSpi
              org.bouncycastle.jcajce.provider.asymmetric.mldsa.HashSignatureSpi.MLDSAExtHash

Direct Known Subclasses:

HashSignatureSpi.MLDSA44ExtHash, HashSignatureSpi.MLDSA65ExtHash, HashSignatureSpi.MLDSA87ExtHash

Enclosing class:

HashSignatureSpi

public static class HashSignatureSpi.MLDSAExtHash

extends HashSignatureSpi

External-hash form of HashML-DSA: bytes passed to Signature.update([]) are treated as the pre-computed message digest, dispatched to HashMLDSASigner.generateSignature(byte[]) / HashMLDSASigner.verifySignature(byte[], byte[]). Counterpart to SignatureSpi.MLDSAExtMu (see github #2198).
