Class TransItem

java.lang.Object
  org.bouncycastle.cert.ct.TransItem

public class TransItem

extends java.lang.Object

One TLS-encoded item from an RFC 9162 (CT v2) TransItemList. The structure is a 2-byte followed by the type-specific payload; this class retains the payload as opaque bytes and provides a typed decoder for the only payload kind the certificate-side decoder needs to interpret in practice: getSignedCertificateTimestampDataV2(). Other payload kinds (log entries, signed tree heads, consistency / inclusion proofs) are still recoverable through getRawData(); layering structured decoders on top is intentionally left to consumers that need them. enum { x509_entry_v2(0x0100), precert_entry_v2(0x0101), x509_sct_v2(0x0102), precert_sct_v2(0x0103), signed_tree_head_v2(0x0104), consistency_proof_v2(0x0105), inclusion_proof_v2(0x0106), reserved_rfc6962(0x0000..0x00FF), reserved_experimentaluse(0xE000..0xEFFF), reserved_privateuse(0xF000..0xFFFF), (0xFFFF) } VersionedTransType; struct { VersionedTransType versioned_type; select (versioned_type) { case x509_sct_v2: SignedCertificateTimestampDataV2; case precert_sct_v2: SignedCertificateTimestampDataV2; [] } data; } TransItem;

Constructor Detail

TransItem

public TransItem(int versionedType,
                 byte[] data)

Method Detail

getInstance

public static TransItem getInstance(byte[] encoded)

Decode a TransItem from its serialized form (the bytes that appear as one entry inside a TransItemList).

getVersionedType

public int getVersionedType()

getRawData

public byte[] getRawData()

The raw payload bytes — i.e. the SerializedTransItem minus the 2-byte versioned_type prefix. The caller is responsible for parsing them according to getVersionedType().

getSignedCertificateTimestampDataV2

public SignedCertificateTimestampDataV2 getSignedCertificateTimestampDataV2()

When this item is a v2 SCT ( or ), return the decoded payload; otherwise return .

getEncoded

public byte[] getEncoded()

Serialize this TransItem to its TLS wire form.
