    <summary>Abstract class for X.</summary>
    <remarks>
      <para>Abstract class for X.509 v1 certificates. This provides a standard
            way to access all the version 1 attributes of an X.509 certificate.
            Attributes that are specific to X.509 v2 or v3 are not available
            through this interface. Future API evolution will provide full access to
            complete X.509 v3 attributes.</para>
      <para>The basic X.509 format was defined by
            ISO/IEC and ANSI X9 and is described below in ASN.1:</para>
      <code lang="text/java">Certificate  ::=  SEQUENCE  {
                tbsCertificate       TBSCertificate,
                signatureAlgorithm   AlgorithmIdentifier,
                signature            BIT STRING  }
            </code>
      <para>These certificates are widely used to support authentication and
            other functionality in Internet security systems. Common applications
            include Privacy Enhanced Mail (PEM), Transport Layer Security (SSL),
            code signing for trusted software distribution, and Secure Electronic
            Transactions (SET).</para>
      <para>These certificates are managed and vouched for by &lt;em&gt;Certificate
            Authorities&lt;/em&gt; (CAs). CAs are services which create certificates by
            placing data in the X.509 standard format and then digitally signing
            that data. CAs act as trusted third parties, making introductions
            between principals who have no direct knowledge of each other.
            CA certificates are either signed by themselves, or by some other
            CA such as a "root" CA.</para>
      <para>The ASN.1 definition of <c>tbsCertificate</c> is:</para>
      <code lang="text/java">TBSCertificate  ::=  SEQUENCE  {
                version         [0]  EXPLICIT Version DEFAULT v1,
                serialNumber         CertificateSerialNumber,
                signature            AlgorithmIdentifier,
                issuer               Name,
                validity             Validity,
                subject              Name,
                subjectPublicKeyInfo SubjectPublicKeyInfo,
                }
            </code>
      <para>Here is sample code to instantiate an X.509 certificate:</para>
      <code lang="text/java">InputStream inStream = new FileInputStream("fileName-of-cert");
            X509Certificate cert = X509Certificate.getInstance(inStream);
            inStream.close();
            </code>
      <para>OR</para>
      <code lang="text/java">byte[] certData = &amp;lt;certificate read from a file, say&amp;gt;
            X509Certificate cert = X509Certificate.getInstance(certData);
            </code>
      <para>In either case, the code that instantiates an X.509 certificate
            consults the value of the <c>cert.provider.x509v1</c> security property
            to locate the actual implementation or instantiates a default implementation.</para>
      <para>The <c>cert.provider.x509v1</c> property is set to a default
            implementation for X.509 such as:</para>
      <code lang="text/java">cert.provider.x509v1=com.sun.security.cert.internal.x509.X509V1CertImpl
            </code>
      <para>The value of this <c>cert.provider.x509v1</c> property has to be
            changed to instantiate another implementation. If this security
            property is not set, a default implementation will be used.
            Currently, due to possible security restrictions on access to
            Security properties, this value is looked up and cached at class
            initialization time and will fallback on a default implementation if
            the Security property is not accessible.</para>
      <para>&lt;em&gt;Note: The classes in the package <c>javax.security.cert</c>
            exist for compatibility with earlier versions of the
            Java Secure Sockets Extension (JSSE). New applications should instead
            use the standard Java SE certificate classes located in
            <c>java.security.cert</c>.&lt;/em&gt;</para>
