Enclosing class:

JcaMTCCosigner

public static class JcaMTCCosigner.Builder
extends Object

Builder for JcaMTCCosigner. Selects the JCA provider used to obtain the underlying Signature instance; the draft algorithm identifier is detected from the private key type at build(byte[], PrivateKey) time.

• ECPrivateKey with a 256-bit order → ECDSA-P256-SHA256
• ECPrivateKey with a 384-bit order → ECDSA-P384-SHA384
• getAlgorithm() equal to "Ed25519" or "EdDSA" → Ed25519
• getAlgorithm() equal to "ML-DSA-44" / "ML-DSA-65" / "ML-DSA-87" → same string

Callers who need to override the detected algorithm string can use the explicit build(String, byte[], PrivateKey) overload.

JcaMTCCosigner	build(String algorithm, byte[] cosignerId, PrivateKey privateKey)	Explicit-algorithm overload for cases where the key-type detection in build(byte[], PrivateKey) doesn't apply (e.g. a key whose getAlgorithm() doesn't carry the MTC algorithm name).

setProvider

public JcaMTCCosigner.Builder setProvider(Provider provider)

build

public JcaMTCCosigner build(byte[] cosignerId,
 PrivateKey privateKey)

Parameters:

cosignerId - binary trust anchor ID of this cosigner — the CA's own trust anchor ID when the CA itself cosigns (Section 5.3); the cosigner's own trust anchor ID otherwise

privateKey - JCA private key whose algorithm determines the MTC signature algorithm string (see class javadoc)

Throws:

IllegalArgumentException - if the private key type is unsupported

build

public JcaMTCCosigner build(String algorithm,
 byte[] cosignerId,
 PrivateKey privateKey)

Explicit-algorithm overload for cases where the key-type detection in build(byte[], PrivateKey) doesn't apply (e.g. a key whose getAlgorithm() doesn't carry the MTC algorithm name).

Parameters:

algorithm - one of the MTCSignatureAlgorithm constants

cosignerId - binary trust anchor ID of this cosigner — the CA's own trust anchor ID when the CA itself cosigns (Section 5.3); the cosigner's own trust anchor ID otherwise

privateKey - JCA private key for algorithm
