Class C509Extension

java.lang.Object
org.bouncycastle.cbor.c509.C509Extension
public class C509Extension extends Object
A single C509 extension (Section 3.1.10 of draft-ietf-cose-cbor-encoded-cert-20): 
Extension = ( ( extensionID: int, extensionValue: Defined ) //
              ( extensionID: ~oid, extensionValue: bytes / [ bytes ] ) )
For the int-coded form the absolute value of the int is the C509 Extensions Registry value, the sign carries criticality (negative for critical), and the value is the specific CBOR encoding of Section 3.3. For the generic form the value is the extnValue OCTET STRING value field, wrapped in a single element array when the extension is critical.

Both forms materialize the DER encoding of the extension value at construction, so an instance always answers getExtnId() and getExtnValue() regardless of the wire form used.
