Remarks

This interface represents an X.509 extension.

Extensions provide a means of associating additional attributes with users or public keys and for managing a certification hierarchy. The extension format also allows communities to define private extensions to carry information unique to those communities.

Each extension contains an object identifier, a criticality setting indicating whether it is a critical or a non-critical extension, and and an ASN.1 DER-encoded value. Its ASN.1 definition is:

Extension ::= SEQUENCE {
                    extnId        OBJECT IDENTIFIER,
                    critical      BOOLEAN DEFAULT FALSE,
                    extnValue     OCTET STRING
                            -- contains a DER encoding of a value
                            -- of the type registered for use with
                            -- the extnId object identifier value
                }

This interface is designed to provide access to a single extension, unlike java.security.cert.X509Extension which is more suitable for accessing a set of extensions.

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
Id
IsCritical
JniIdentityHashCode	Returns the value of java.lang.System.identityHashCode() for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls Dispose(); otherwise, does nothing. (Inherited from IJavaPeerable)
Encode(Stream)	Generates the extension's DER encoding and writes it to the output stream.
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
GetValue()	Gets the extensions's DER-encoded value.
SetJniIdentityHashCode(Int32)	Set the value returned by JniIdentityHashCode. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by PeerReference. (Inherited from IJavaPeerable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)
