Examples of org.bouncycastle.asn1.x509.TBSCertificateStructure

org.bouncycastle.asn1.x509.SubjectPublicKeyInfo

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.
