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).
