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.

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.

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.

PKIXCertPathValidatorResult This class represents the successful result of the PKIX certification path validation algorithm. 
PKIXParameters Parameters used as input for the PKIX CertPathValidator algorithm.

X509Certificate

Abstract class for X.509 certificates.
