Class CompositeIndex

java.lang.Object

org.bouncycastle.jcajce.provider.asymmetric.compositekem.CompositeIndex

public class CompositeIndex
extends Object

Registry of the Composite ML-KEM parameter sets from Composite ML-KEM for use in X.509 Public Key Infrastructure. For each composite OID it holds the component algorithm pair, the human-readable algorithm name, and the KEM combiner domain separator ("Label") used in section 3.4.

Method Details

getKeyPairSpecs

public static AlgorithmParameterSpec[] getKeyPairSpecs(ASN1ObjectIdentifier algorithm)

Per-component AlgorithmParameterSpecs used to initialise the component KeyPairGenerators, in pairing order. Every entry is non-null: the specs are also the only route a caller-supplied SecureRandom has to a component generator.

getSupportedIdentifiers

public static Set<ASN1ObjectIdentifier> getSupportedIdentifiers()

getAlgorithmName

public static String getAlgorithmName(ASN1ObjectIdentifier algorithm)

getPairing

public static String[] getPairing(ASN1ObjectIdentifier algorithm)

getAlgorithmAliases

public static String[] getAlgorithmAliases(ASN1ObjectIdentifier algorithm)

Additional names a composite KEM algorithm is registered under, beyond the one getAlgorithmName(org.bouncycastle.asn1.ASN1ObjectIdentifier) returns. Empty for every parameter set that has only one name.

isCompositeKEMOID

public static boolean isCompositeKEMOID(ASN1ObjectIdentifier oid)

Check if OID is a Composite KEM OID.

getKEMLabel

public static byte[] getKEMLabel(ASN1ObjectIdentifier oid)

Get the KEM combiner domain separator ("Label") for a Composite KEM OID (section 3.4 / section 6).

getTraditionalAlgorithmName

public static String getTraditionalAlgorithmName(ASN1ObjectIdentifier oid)

Get the traditional algorithm component name for a Composite KEM OID.
