java.security.cert

Provides classes and interfaces for parsing and managing certificates, certificate revocation lists (CRLs), and certification paths. It contains support for X.509 v3 certificates and X.509 v2 CRLs.

Package Specification

For information about X.509 certificates and CRLs, please see:

Interfaces

CertPathBuilderResult A specification of the result of a certification path builder algorithm.  CertPathChecker Performs one or more checks on each Certificate of a CertPath.  CertPathParameters A specification of certification path algorithm parameters.  CertPathValidatorException.Reason The reason the validation algorithm failed.  CertPathValidatorResult A specification of the result of a certification path validator algorithm.  CertSelector A selector that defines a set of criteria for selecting Certificates.  CertStoreParameters A specification of CertStore parameters.  CRLSelector A selector that defines a set of criteria for selecting CRLs.  Extension This interface represents an X.509 extension.  PolicyNode An immutable valid policy tree node as defined by the PKIX certification path validation algorithm.  X509Extension Interface for an X.509 extension. 

Classes

Certificate Abstract class for managing a variety of identity certificates.  Certificate.CertificateRep Alternate Certificate class for serialization.  CertificateFactory This class defines the functionality of a certificate factory, which is used to generate certificate, certification path (CertPath) and certificate revocation list (CRL) objects from their encodings.  CertificateFactorySpi This class defines the Service Provider Interface (SPI) for the CertificateFactory class.  CertPath An immutable sequence of certificates (a certification path).  CertPath.CertPathRep Alternate CertPath class for serialization.  CertPathBuilder A class for building certification paths (also known as certificate chains).  CertPathBuilderSpi The Service Provider Interface (SPI) for the CertPathBuilder class.  CertPathValidator A class for validating certification paths (also known as certificate chains).  CertPathValidatorSpi The Service Provider Interface (SPI) for the CertPathValidator class.  CertStore A class for retrieving Certificates and CRLs from a repository.  CertStoreSpi The Service Provider Interface (SPI) for the CertStore class.  CollectionCertStoreParameters Parameters used as input for the Collection CertStore algorithm.  CRL This class is an abstraction of certificate revocation lists (CRLs) that have different formats but important common uses.  LDAPCertStoreParameters Parameters used as input for the LDAP CertStore algorithm.  PKIXBuilderParameters Parameters used as input for the PKIX CertPathBuilder algorithm.  PKIXCertPathBuilderResult This class represents the successful result of the PKIX certification path builder algorithm.  PKIXCertPathChecker An abstract class that performs one or more checks on an X509Certificate.  PKIXCertPathValidatorResult This class represents the successful result of the PKIX certification path validation algorithm.  PKIXParameters Parameters used as input for the PKIX CertPathValidator algorithm.  PKIXRevocationChecker A PKIXCertPathChecker for checking the revocation status of certificates with the PKIX algorithm.  PolicyQualifierInfo An immutable policy qualifier represented by the ASN.1 PolicyQualifierInfo structure.  TrustAnchor A trust anchor or most-trusted Certification Authority (CA).  URICertStoreParameters Parameters used as input for CertStore algorithms which use information contained in a URI to retrieve certificates and CRLs.  X509Certificate Abstract class for X.509 certificates.  X509CertSelector A CertSelector that selects X509Certificates that match all specified criteria.  X509CRL Abstract class for an X.509 Certificate Revocation List (CRL).  X509CRLEntry

Abstract class for a revoked certificate in a CRL (Certificate Revocation List).  X509CRLSelector A CRLSelector that selects X509CRLs that match all specified criteria. 

Enums

CertPathValidatorException.BasicReason The BasicReason enumerates the potential reasons that a certification path of any type may be invalid. 
CRLReason The CRLReason enumeration specifies the reason that a certificate is revoked, as defined in RFC 5280: Internet X.509 Public Key Infrastructure Certificate and CRL Profile. 
PKIXReason The PKIXReason enumerates the potential PKIX-specific reasons that an X.509 certification path may be invalid according to the PKIX (RFC 5280) standard. 
PKIXRevocationChecker.Option Various revocation options that can be specified for the revocation checking mechanism.
