CertificateList (Bouncy Castle Library 1.85 API Specification)
Date: 2026-07-12

org.bouncycastle.asn1.x509

## Class CertificateList

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

- All Implemented Interfaces:
    ASN1Encodable, Encodable

      public class CertificateList
      extends ASN1Object

  PKIX RFC-2459 The X.509 v2 CRL syntax is as follows. For signature calculation, the data that is to be signed is ASN.1 DER encoded.

       CertificateList  ::=  SEQUENCE  {
            tbsCertList          TBSCertList,
            signatureAlgorithm   AlgorithmIdentifier,
            signatureValue       BIT STRING  }
