Class CertificateFactory

java.lang.Object

java.security.cert.CertificateFactorySpi

iaik.x509.CertificateFactory

Direct Known Subclasses:

QualifiedCertificateFactory, X509CertificateFactory

public class CertificateFactory
extends java.security.cert.CertificateFactorySpi

This class implements a CertificateFactory for X.509.

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

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

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

Subsequently use the generateCertificate, generateCertificates, generateCRL, or generateCRLs method for pasrsing a X.509 certificate, a collection of X.509 certificates, a X.509 CRL, or a collection of X.509 CRLs, respectively, e.g.:

 Collection c = certFactory.generateCertificates(is);

engineGenerateCertificate

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

Parses a X.509 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 X509Certificate 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)

4. NetscapeCertList

Specified by:

engineGenerateCertificates in class java.security.cert.CertificateFactorySpi

Parameters:

is - the input stream supplying the encoded certificates

Returns:

the collection of X509Certificates parsed from the stream

Throws:

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

engineGenerateCRL

1. PKCS7CRLList
2. Chain of DER encoded X.509 CRLs

Specified by:

engineGenerateCRLs in class java.security.cert.CertificateFactorySpi

Parameters:

is - the input stream supplying the encoded CRLs

Returns:

the collection of X509CRLs parsed from the stream
