SignedCertificateTimestampDataV2 (Bouncy Castle Library 1.85 API Specification)

java.lang.Object
- org.bouncycastle.cert.ct.SignedCertificateTimestampDataV2

```
public class SignedCertificateTimestampDataV2
extends java.lang.Object
```
The SCT body carried inside an RFC 9162 (CT v2) TransItem whose versioned_type is x509_sct_v2 (0x0102) or precert_sct_v2 (0x0103).
```
     struct {
         LogID    log_id;                       // opaque LogID<2..127>
         uint64   timestamp;
         Extension sct_extensions<0..2^16-1>;
         opaque   signature<1..2^16-1>;
     } SignedCertificateTimestampDataV2;
 
```
Notable differences vs the RFC 6962 v1 SignedCertificateTimestamp: the log identifier is variable-length (a 1-byte length prefix preceding 2-127 bytes, not a fixed 32-byte SHA-256); sct_extensions is a structured list of SctExtension entries rather than an opaque blob; the signature is plain opaque bytes (no embedded hash / signature algorithm pair — the verifier discovers the algorithm from the log's published key).

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`byte[]`	`getEncoded()`	Serialize this v2 SCT body to its TLS wire form (the bytes that would form the `data` field of the containing TransItem).
`static SignedCertificateTimestampDataV2`	`getInstance(byte[] encoded)`	Decode the v2 SCT body from its serialized TLS form (the bytes of the containing `TransItem.data` field, after the 2-byte versioned_type prefix has been stripped).
`byte[]`	`getLogID()`	Variable-length log identifier (2..127 bytes).
`java.util.List`	`getSctExtensions()`	Decoded `sct_extensions` entries; never `null`.
`byte[]`	`getSignature()`	Raw signature bytes.
`long`	`getTimestamp()`	Issuance timestamp in milliseconds since the Unix epoch.
