Class AttributeCertificateFactory

java.lang.Object

java.security.cert.CertificateFactorySpi

iaik.x509.attr.AttributeCertificateFactory

public class AttributeCertificateFactory
extends java.security.cert.CertificateFactorySpi

This class implements a CertificateFactory for X.509 Attribute Certificates.

Certificate Factories are used for reading encoded certificates and Certificate Revocation Lists (CRLs) from input streams.

For instantiating the IAIK attribute certificate factory call the getInstance factory method of the java.security.cert.CertificateFactory engine class, thereby supplying the certificate type ("X.509 AC") and the name of the IAIK provider:

 CertifiacteFactory certFactory = CertificateFactory
     .getInstance("X.509 AC", "IAIK");
 

Subsequently use the generateCertificate, generateCertificates, generateCRL, or generateCRLs method for parsing a X.509 attribute certificate, a collection of X.509 attribute certificates, a X.509 ACRL, or a collection of X.509 ACRLs, respectively, e.g.:

 Collection c = certFactory.generateCertificates(is);

Method Detail

engineGenerateCertificate

public java.security.cert.Certificate engineGenerateCertificate(java.io.InputStream is)
                                                         throws java.security.cert.CertificateException

Parses an X.509 attribute certificate from the supplied input stream.

Specified by:

engineGenerateCertificate in class java.security.cert.CertificateFactorySpi

Parameters:

is - the input stream supplying the encoded certificate

Returns:

the AttributeCertificate parsed from the stream

Throws:

java.security.cert.CertificateException - if an decoding/parsing error occurs

engineGenerateCertificates

public java.util.Collection engineGenerateCertificates(java.io.InputStream is)
                                                throws java.security.cert.CertificateException

Parses a collection of X.509 attribute certificates from the supplied input stream. The collection may be supplied list of DER encoded X.509 attribute certificates (DER, PEM, or base64 encoded).

Specified by:

engineGenerateCertificates in class java.security.cert.CertificateFactorySpi

Parameters:

is - the input stream supplying the encoded attribute certificates

Returns:

the collection of AttributeCertificates parsed from the stream

Throws:

java.security.cert.CertificateException - if an decoding/parsing error occurs

engineGenerateCRL

public java.security.cert.CRL engineGenerateCRL(java.io.InputStream is)
                                         throws java.security.cert.CRLException

Parses a X.509 attribute CRL from the supplied input stream.

Specified by:

engineGenerateCRL in class java.security.cert.CertificateFactorySpi

Parameters:

is - the input stream supplying the encoded ACRL

Returns:

the ACRL parsed from the stream

Throws:

java.security.cert.CRLException - if an decoding/parsing error occurs

engineGenerateCRLs

public java.util.Collection engineGenerateCRLs(java.io.InputStream is)
                                        throws java.security.cert.CRLException

Parses a collection of X.509 attribute CRLs from the supplied input stream. The collection may be supplied as list of DER/PEM/base64 encoded ACRLs.

Specified by:

engineGenerateCRLs in class java.security.cert.CertificateFactorySpi

Parameters:

is - the input stream supplying the encoded ACRLs

Returns:

the collection of ACRLs parsed from the stream

Throws:

java.security.cert.CRLException - if an decoding/parsing error occurs
