The purpose of these functions is to flush or to retrieve a time valid object (CTL, CRL, or certificate). Since objects have a valid time duration, it is possible for an object to expire and no longer be valid. An object is valid only for the period of time specified by the Certification Authority (CA) that issued the certificate.
The following functions are included in this category and the signatures can be found in Wincrypt.h.
| Function | Description |
|---|---|
| CryptFlushTimeValidObject | Removes the retrieved object from the cache. |
| CryptGetTimeValidObject | Gets the object whose validity period covers the specified time value. |
