<DL>
<DD>Generates a certificate object and initializes it with
 the data read from the input stream <code>inStream</code>.

 <p>The given input stream <code>inStream</code> must contain a single
 certificate.

 <p>In order to take advantage of the specialized certificate format
 supported by this certificate factory,
 the returned certificate object can be typecast to the corresponding
 certificate class. For example, if this certificate
 factory implements X.509 certificates, the returned certificate object
 can be typecast to the <code>X509Certificate</code> class.

 <p>In the case of a certificate factory for X.509 certificates, the
 certificate provided in <code>inStream</code> must be DER-encoded and
 may be supplied in binary or printable (Base64) encoding. If the
 certificate is provided in Base64 encoding, it must be bounded at
 the beginning by -----BEGIN CERTIFICATE-----, and must be bounded at
 the end by -----END CERTIFICATE-----.

 <p>Note that if the given input stream does not support
 <A HREF="../../../java/io/InputStream.html#mark(int)"><CODE>mark</CODE></A> and
 <A HREF="../../../java/io/InputStream.html#reset()"><CODE>reset</CODE></A>, this method will
 consume the entire input stream.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>inStream</CODE> - an input stream with the certificate data.<DT><B>Returns:</B><DD>a certificate object initialized with the data
 from the input stream.<DT><B>Throws:</B><DD><CODE><A HREF="../../../java/security/cert/CertificateException.html">CertificateException</A></CODE> - on parsing errors.</DL>

                                               throws <A HREF="../../../java/security/cert/CertificateException.html">CertificateException</A></PRE>
<DL>
<DD>Returns a (possibly empty) collection view of the certificates read
 from the given input stream <code>inStream</code>.

 <p>In order to take advantage of the specialized certificate format
 supported by this certificate factory, each element in
 the returned collection view can be typecast to the corresponding
 certificate class. For example, if this certificate
 factory implements X.509 certificates, the elements in the returned
 collection can be typecast to the <code>X509Certificate</code> class.

 <p>In the case of a certificate factory for X.509 certificates,
 <code>inStream</code> may contain a single DER-encoded certificate
 in the formats described for 
 <A HREF="../../../java/security/cert/CertificateFactory.html#generateCertificate(java.io.InputStream)"><CODE>generateCertificate</CODE></A>.
 In addition, <code>inStream</code> may contain a PKCS#7 certificate
 chain. This is a PKCS#7 <i>SignedData</i> object, with the only
 significant field being <i>certificates</i>. In particular, the
 signature and the contents are ignored. This format allows multiple
 certificates to be downloaded at once. If no certificates are present,
 an empty collection is returned.

 <p>Note that if the given input stream does not support
 <A HREF="../../../java/io/InputStream.html#mark(int)"><CODE>mark</CODE></A> and
 <A HREF="../../../java/io/InputStream.html#reset()"><CODE>reset</CODE></A>, this method will
 consume the entire input stream.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>inStream</CODE> - the input stream with the certificates.<DT><B>Returns:</B><DD>a (possibly empty) collection view of

                               throws <A HREF="../../../java/security/cert/CRLException.html">CRLException</A></PRE>
<DL>
<DD>Generates a certificate revocation list (CRL) object and initializes it
 with the data read from the input stream <code>inStream</code>.

 <p>In order to take advantage of the specialized CRL format
 supported by this certificate factory,
 the returned CRL object can be typecast to the corresponding
 CRL class. For example, if this certificate
 factory implements X.509 CRLs, the returned CRL object
 can be typecast to the <code>X509CRL</code> class.

 <p>Note that if the given input stream does not support
 <A HREF="../../../java/io/InputStream.html#mark(int)"><CODE>mark</CODE></A> and

<DL>
<DD>Returns a (possibly empty) collection view of the CRLs read
 from the given input stream <code>inStream</code>.

 the returned collection view can be typecast to the corresponding
 CRL class. For example, if this certificate

 set. This is a PKCS#7 <i>SignedData</i> object, with the only
