|---|---|---|
| REG_DWORD | 0x0 - 0xFFFFFFFF keys | 0x7F (127) |
Determines the maximum number of symmetric encryption keys found in incoming messages that can be stored in the cryptographic key cache on the receiving server.
If the cache is full (that is, the number of incoming keys is equal to the value of the CryptReceiveKeyCacheSize entry) when the next certificate arrives, Message Queuing deletes half of the certificates in the cache. The oldest certificates are deleted first.
Note
Incoming keys in the cryptographic key cache are not subject to an expiration time. Incoming keys are deleted from the cache only when the cache is full.
Windows 2000 does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry.
