PKIXCertPathChecker

extends Object
implements Cloneable
java.lang.Object
   ↳ java.security.cert.PKIXCertPathChecker

Class Overview

The class specifying the interface to extend the certification path validation algorithm by checks to perform on an X509Certificate.

The checks are added to a certification path validation using the setCertPathCheckers or addCertPathChecker of the PKIXParameters and PKIXBuilderParameters class respectively. The check method will be called for each certificate processed by a CertPathBuilder of CertPathValidator.

A PKIXCertPathChecker implementation must support reverse checking (from trusted CA to target) and may support forward checking (from target to trusted CA). The return value of isForwardCheckingSupported indicates whether forward checking is supported.

Protected Constructors

protected PKIXCertPathChecker ()

Added in API level 1

Creates a new PKIXCertPathChecker instance.

Public Methods

public abstract void check (Certificate cert, Collection<String> unresolvedCritExts)

Added in API level 1

Checks the specified certificate and removes the processed critical extensions from the specified list of X.509 extension OIDs.

Parameters
cert Certificate: the certificate.
unresolvedCritExts Collection: the list of critical X.509 extension OID strings.
Throws
CertPathValidatorException if check(s) fail on the specified certificate.

public Object clone ()

Added in API level 1

Clones this PKIXCertPathChecker instance.

Returns
Object the cloned instance.

public abstract Set<String> getSupportedExtensions ()

Added in API level 1

Returns the list of extensions of X.509 certificates that this PKIXCertPathChecker is able to process.

Returns
Set<String> the list of extensions of X.509 certificates that this PKIXCertPathChecker is able to process, or null if there are none.

public abstract void init (boolean forward)

Added in API level 1

Initializes this PKIXCertPathChecker instance for specified checking direction.

Parameters
forward boolean: the direction of the certification path processing, true if the certificates are processed in forward direction (from target to trusted CA), false if processed in reverse direction (from trusted CA to target).
Throws
CertPathValidatorException if initialization of this PKIXCertPathChecker instance fails, or if it cannot process certificates in the specified order.

public abstract boolean isForwardCheckingSupported ()

Added in API level 1

Returns whether this PKIXCertPathChecker instance supports forward checking.

Returns
boolean true if this PKIXCertPathChecker instance supports forward checking, otherwise false.
