## Class LinkedCertificate

- java.lang.Object
- - org.bouncycastle.asn1.ASN1Object
  - - org.bouncycastle.asn1.bc.LinkedCertificate

- All Implemented Interfaces:
    ASN1Encodable, Encodable

      public class LinkedCertificate
      extends ASN1Object

  Extension to tie an alternate certificate to the containing certificate.

           LinkedCertificate := SEQUENCE {
               digest        DigestInfo,                   -- digest of PQC certificate
               certLocation  GeneralName,                  -- location of PQC certificate
               certIssuer    [0] Name OPTIONAL,            -- issuer of PQC cert (if different from current certificate)
               cACerts       [1] GeneralNames OPTIONAL,    -- CA certificates for PQC cert (one of more locations)
       }
