Remarks

A PKIXCertPathChecker for checking the revocation status of certificates with the PKIX algorithm.

A PKIXRevocationChecker checks the revocation status of certificates with the Online Certificate Status Protocol (OCSP) or Certificate Revocation Lists (CRLs). OCSP is described in RFC 2560 and is a network protocol for determining the status of a certificate. A CRL is a time-stamped list identifying revoked certificates, and RFC 5280 describes an algorithm for determining the revocation status of certificates using CRLs.

Each PKIXRevocationChecker must be able to check the revocation status of certificates with OCSP and CRLs. By default, OCSP is the preferred mechanism for checking revocation status, with CRLs as the fallback mechanism. However, this preference can be switched to CRLs with the Option#PREFER_CRLS PREFER_CRLS option. In addition, the fallback mechanism can be disabled with the Option#NO_FALLBACK NO_FALLBACK option.

A PKIXRevocationChecker is obtained by calling the CertPathValidator#getRevocationChecker getRevocationChecker method of a PKIX CertPathValidator. Additional parameters and options specific to revocation can be set (by calling the #setOcspResponder setOcspResponder method for instance). The PKIXRevocationChecker is added to a PKIXParameters object using the PKIXParameters#addCertPathChecker addCertPathChecker or PKIXParameters#setCertPathCheckers setCertPathCheckers method, and then the PKIXParameters is passed along with the CertPath to be validated to the CertPathValidator#validate validate method of a PKIX CertPathValidator. When supplying a revocation checker in this manner, it will be used to check revocation irrespective of the setting of the PKIXParameters#isRevocationEnabled RevocationEnabled flag. Similarly, a PKIXRevocationChecker may be added to a PKIXBuilderParameters object for use with a PKIX CertPathBuilder.

Note that when a PKIXRevocationChecker is added to PKIXParameters, it clones the PKIXRevocationChecker; thus any subsequent modifications to the PKIXRevocationChecker have no effect.

Any parameter that is not set (or is set to null) will be set to the default value for that parameter.

<b>Concurrent Access</b>

Unless otherwise specified, the methods defined in this class are not thread-safe. Multiple threads that need to access a single object concurrently should synchronize amongst themselves and provide the necessary locking. Multiple threads each manipulating separate objects need not synchronize.
