public sealed class X509Extension : IMessage<X509Extension>, IEquatable<X509Extension>, IDeepCloneable<X509Extension>, IBufferMessage, IMessage
An [X509Extension][google.cloud.security.privateca.v1.X509Extension] specifies an X.509 extension, which may be used in
different parts of X.509 objects like certificates, CSRs, and CRLs.
