/*

* FUNCTION: pkix_ExpirationChecker_Initialize
|
|
* DESCRIPTION:
|
|
*
|
|
* Creates a new CertChainChecker and stores it at "pChecker", where it will
|
|
* used by pkix_ExpirationChecker_Check to check that the certificate has not
|
|
* expired with respect to the Date pointed to by "testDate." If "testDate"
|
|
* is NULL, then the CertChainChecker will check that a certificate has not
|
|
* expired with respect to the current date and time.
|
|
*
|
|
* PARAMETERS:
|
|
* "testDate"
|
|
* Address of Date representing the point in time at which the cert is to
|
|
* be validated. If "testDate" is NULL, the current date and time is used.
|
|
* "pChecker"
|
|
* Address where object pointer will be stored. Must be non-NULL.
|
|
* "plContext"
|
|
* Platform-specific context pointer.
|
|
* THREAD SAFETY:
|
|
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
|
|
* RETURNS:
|
|
* Returns NULL if the function succeeds.
|
|
* Returns a CertChainChecker Error if the function fails in a non-fatal way.
|
|
* Returns a Fatal Error if the function fails in an unrecoverable way.
