Known Direct Subclasses |
This class defines the Service Provider Interface (SPI)
for the CertificateFactory
class.
All the abstract methods in this class must be implemented by each
cryptographic service provider who wishes to supply the implementation
of a certificate factory for a particular certificate type, e.g., X.509.
Certificate factories are used to generate certificate, certification path
(CertPath
) and certificate revocation list (CRL) objects from
their encodings.
A certificate factory for X.509 must return certificates that are an
instance of java.security.cert.X509Certificate
, and CRLs
that are an instance of java.security.cert.X509CRL
.

From class
java.lang.Object
|
Generates a certificate revocation list (CRL) object and initializes it
with the data read from the input stream inStream
.
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 X509CRL
class.
Note that if the given input stream does not support
mark
and
reset
, this method will
consume the entire input stream. Otherwise, each call to this
method consumes one CRL and the read position of the input stream
is positioned to the next available byte after the the inherent
end-of-CRL marker. If the data in the
input stream does not contain an inherent end-of-CRL marker (other
than EOF) and there is trailing data after the CRL is parsed, a
CRLException
is thrown.
inStream | an input stream with the CRL data. |

CRLException | on parsing errors. |

Returns a (possibly empty) collection view of the CRLs read
from the given input stream inStream
.
In order to take advantage of the specialized CRL format
supported by this certificate factory, each element in
the returned collection view can be typecast to the corresponding
CRL class. For example, if this certificate
factory implements X.509 CRLs, the elements in the returned
collection can be typecast to the X509CRL
class.
In the case of a certificate factory for X.509 CRLs,
inStream
may contain a single DER-encoded CRL.
In addition, inStream
may contain a PKCS#7 CRL
set. This is a PKCS#7 SignedData object, with the only
significant field being crls. In particular, the
signature and the contents are ignored. This format allows multiple
CRLs to be downloaded at once. If no CRLs are present,
an empty collection is returned.
Note that if the given input stream does not support
mark
and
reset
, this method will
consume the entire input stream.

Generates a CertPath
object and initializes it with
the data read from the InputStream
inStream. The data
is assumed to be in the specified encoding.
This method was added to version 1.4 of the Java 2 Platform
Standard Edition. In order to maintain backwards compatibility with
existing service providers, this method cannot be abstract
and by default throws an UnsupportedOperationException
.

The certificates supplied must be of a type supported by the
CertificateFactory
. They will be copied out of the supplied
List
object.

Generates a certificate object and initializes it with
the data read from the input stream inStream
.
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 X509Certificate
class.
In the case of a certificate factory for X.509 certificates, the
certificate provided in inStream
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-----.
Note that if the given input stream does not support
mark
and
reset
, this method will
consume the entire input stream. Otherwise, each call to this
method consumes one certificate and the read position of the input stream
is positioned to the next available byte after the the inherent
end-of-certificate marker. If the data in the
input stream does not contain an inherent end-of-certificate marker (other
than EOF) and there is trailing data after the certificate is parsed, a
CertificateException
is thrown.
inStream | an input stream with the certificate data. |

Returns a (possibly empty) collection view of the certificates read
from the given input stream inStream
.
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 X509Certificate
class.
In the case of a certificate factory for X.509 certificates,
inStream
may contain a single DER-encoded certificate
in the formats described for
generateCertificate
.
In addition, inStream
may contain a PKCS#7 certificate
chain. This is a PKCS#7 SignedData object, with the only
significant field being certificates. 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.
Note that if the given input stream does not support
mark
and
reset
, this method will
consume the entire input stream.

Returns an iteration of the CertPath
encodings supported
by this certificate factory, with the default encoding first. See
Appendix A in the
Java Certification Path API Programmer's Guide
for information about standard encoding names.
Attempts to modify the returned Iterator
via its
remove
method result in an
UnsupportedOperationException
.

existing service providers, this method cannot be abstract
