# Package java.security.cert

Provides classes and interfaces for parsing and managing certificates, certificate revocation lists (CRLs), and certification paths.

See: Description

- Interface Summary
  Interface | Description
  --- | ---
  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 `Certificate`s.
  CertStoreParameters | A specification of `CertStore` parameters.
  CRLSelector | A selector that defines a set of criteria for selecting `CRL`s.
  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.

- Class Summary
  Class | Description
  --- | ---
  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 `Certificate`s and `CRL`s 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).
  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.

- Enum Summary
  Enum | Description
  --- | ---
  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 3280: 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 3280) standard.
  PKIXRevocationChecker.Option | Various revocation options that can be specified for the revocation checking mechanism.

- Exception Summary
  Exception | Description
  --- | ---
  CertificateEncodingException | Certificate Encoding Exception.
  CertificateException | This exception indicates one of a variety of certificate problems.
  CertificateExpiredException | Certificate Expired Exception.
  CertificateNotYetValidException | Certificate is not yet valid exception.
  CertificateParsingException | Certificate Parsing Exception.
  CertificateRevokedException | An exception that indicates an X.509 certificate is revoked.
  CertPathBuilderException | An exception indicating one of a variety of problems encountered when building a certification path with a `CertPathBuilder`.
  CertPathValidatorException | An exception indicating one of a variety of problems encountered when validating a certification path.
  CertStoreException | An exception indicating one of a variety of problems retrieving certificates and CRLs from a `CertStore`.
  CRLException | CRL (Certificate Revocation List) Exception.
