## Class RelatedCertificateDescriptor

- java.lang.Object
- - org.bouncycastle.asn1.ASN1Object
  - - org.bouncycastle.asn1.x509.RelatedCertificateDescriptor

- All Implemented Interfaces:
    ASN1Encodable, Encodable

      public class RelatedCertificateDescriptor
      extends ASN1Object

  Descriptor for a related certificate, as defined by draft-ietf-lamps-certdiscovery (Certificate Discovery in PKIX). Carried as the value of an `OtherName` (type-id `BCObjectIdentifiers.id_on_relatedCertificateDescriptor`) inside the `accessLocation` GeneralName of an `AccessDescription` whose `accessMethod` is `BCObjectIdentifiers.id_ad_certDiscovery`, sitting in turn inside the SubjectInfoAccess extension (`Extension.subjectInfoAccess`).

           RelatedCertificateDescriptor ::= SEQUENCE {
               method               CertDiscoveryMethod,
               intent               DiscoveryIntentId OPTIONAL,
               signatureAlgorithm   [0] IMPLICIT AlgorithmIdentifier OPTIONAL,
               publicKeyAlgorithm   [1] IMPLICIT AlgorithmIdentifier OPTIONAL
           }

           DiscoveryIntentId ::= OBJECT IDENTIFIER

  Intent OIDs are defined under `BCObjectIdentifiers.id_rcd` (placeholder arc pending IANA assignment): `BCObjectIdentifiers.id_rcd_agility`, `BCObjectIdentifiers.id_rcd_redundancy`, `BCObjectIdentifiers.id_rcd_dual`, `BCObjectIdentifiers.id_rcd_priv_key_stmt`, `BCObjectIdentifiers.id_rcd_self`.

    - #### RelatedCertificateDescriptor

          public RelatedCertificateDescriptor(CertDiscoveryMethod method)

  - ### Method Detail

    - #### getInstance

          public static RelatedCertificateDescriptor getInstance(java.lang.Object obj)

    - #### fromExtensions

          public static RelatedCertificateDescriptor[] fromExtensions(Extensions extensions)

      Walk the SubjectInfoAccess extension of the supplied `Extensions` and return every `RelatedCertificateDescriptor` it carries (each AccessDescription whose accessMethod is `BCObjectIdentifiers.id_ad_certDiscovery` and whose accessLocation is an OtherName of type `BCObjectIdentifiers.id_on_relatedCertificateDescriptor`).
      Returns:
        an array, never `null`; empty when the extension is absent or carries no certificate-discovery descriptors.
