| CertPathBuilderSpi | The Service Provider Interface (SPI)
 for the CertPathBuilderclass. | 
| CertPathValidator | A class for validating certification paths (also known as certificate chains). | 
| CertPathValidatorSpi | The Service Provider Interface (SPI)
 for the CertPathValidatorclass. |

 from a repository. | 
| CertStoreSpi | The Service Provider Interface (SPI)
 for the CertStoreclass. | 
| CollectionCertStoreParameters | Parameters used as input for the Collection CertStorealgorithm. | 
| 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 CertStorealgorithm. | 
| PKIXBuilderParameters | Parameters used as input for the PKIX CertPathBuilderalgorithm. | 
| 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 CertPathValidatoralgorithm. | 
| PKIXRevocationChecker | A PKIXCertPathCheckerfor 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 CertStorealgorithms which use
 information contained in a URI to retrieve certificates and CRLs. | 
| X509Certificate | Abstract class for X.509 certificates. | 
| X509CertSelector | A CertSelectorthat selectsX509Certificatesthat
 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 CRLSelectorthat selectsX509CRLsthat
 match all specified criteria. |
