TBSCertificateStructure

public class TBSCertificateStructure extends org.bouncycastle.asn1.ASN1Encodable implements X509ObjectIdentifiers, org.bouncycastle.asn1.pkcs.PKCSObjectIdentifiers
The TBSCertificate object. 
TBSCertificate ::= SEQUENCE {
version [ 0 ] Version DEFAULT v1(0),
serialNumber CertificateSerialNumber,
signature AlgorithmIdentifier,
issuer Name,
validity Validity,
subject Name,
subjectPublicKeyInfo SubjectPublicKeyInfo,
issuerUniqueID [ 1 ] IMPLICIT UniqueIdentifier OPTIONAL,
subjectUniqueID [ 2 ] IMPLICIT UniqueIdentifier OPTIONAL,
extensions [ 3 ] Extensions OPTIONAL
}

Note: issuerUniqueID and subjectUniqueID are both deprecated by the IETF. This class will parse them, but you really shouldn't be creating new ones.
