Class HybridSignatureContexts

java.lang.Object

zeroecho.sdk.hybrid.signature.HybridSignatureContexts

public final class HybridSignatureContexts
extends Object

Factory for SignatureContext-compatible hybrid signature contexts.

The returned contexts implement the standard ZeroEcho streaming contract: wrapping a stream produces/verifies a signature trailer at EOF.

Since:

1.0

Method Summary

Modifier and Type	Method	Description
static SignatureContext	sign(ZeroEchoSession session, HybridSignatureProfile profile, PrivateKey classicPrivate, PrivateKey pqcPrivate, int maxBufferedBytes)	Creates a signing hybrid signature context.
static SignatureContext	verify(ZeroEchoSession session, HybridSignatureProfile profile, PublicKey classicPublic, PublicKey pqcPublic, int maxBufferedBytes)	Creates a verification hybrid signature context.

Method Details

sign

public static SignatureContext sign(ZeroEchoSession session,
 HybridSignatureProfile profile,
 PrivateKey classicPrivate,
 PrivateKey pqcPrivate,
 int maxBufferedBytes)

Creates a signing hybrid signature context.

Parameters:

session - active session used to create both signature contexts

profile - hybrid signature profile

classicPrivate - private key for the classical signature engine

pqcPrivate - private key for the PQC signature engine

maxBufferedBytes - maximum number of bytes buffered from the wrapped stream (DoS guard)

Returns:

signing signature context

Throws:

NullPointerException - if any mandatory argument is null

IllegalArgumentException - if maxBufferedBytes <= 0

UnsupportedRoleException - if either component uses LMS/XMSS, before constructing either child context

Since:

1.0

verify

public static SignatureContext verify(ZeroEchoSession session,
 HybridSignatureProfile profile,
 PublicKey classicPublic,
 PublicKey pqcPublic,
 int maxBufferedBytes)

Creates a verification hybrid signature context.

Parameters:

session - active session used to create both verification contexts

profile - hybrid signature profile

classicPublic - public key for the classical signature engine

pqcPublic - public key for the PQC signature engine

maxBufferedBytes - maximum number of bytes buffered from the wrapped stream (DoS guard)

Returns:

verifying signature context

Throws:

NullPointerException - if any mandatory argument is null

IllegalArgumentException - if maxBufferedBytes <= 0

Since:
