Class JcaMTCCosignerVerifierProvider

java.lang.Object

org.bouncycastle.cert.plants.jcajce.JcaMTCCosignerVerifierProvider

All Implemented Interfaces:

MTCCosignerVerifierProvider

public class JcaMTCCosignerVerifierProvider
extends java.lang.Object
implements MTCCosignerVerifierProvider

JCA-side MTCCosignerVerifierProvider that holds a table of cosigner trust anchor IDs mapped to MTCSignatureVerifier instances.

The convenience JcaMTCCosignerVerifierProvider.Builder.addCosigner(byte[], PublicKey) overload wraps a JCA PublicKey in a JcaMTCSignatureVerifier, auto-detecting the draft algorithm identifier from the key type:

• ECPublicKey with a 256-bit field → ECDSA-P256-SHA256
• ECPublicKey with a 384-bit field → 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 needing a different algorithm string for the same key type, or a verifier from another module (e.g. a lightweight BcMTCSignatureVerifier), can use JcaMTCCosignerVerifierProvider.Builder.addCosigner(byte[], MTCSignatureVerifier) directly.
