Local Security Authority - Client Cipher Routines
|
||
|
|
|

|
|
These routines interface the LSA client side with the Cipher
|
||
|
|
Routines. They perform RPC-style memory allocation.

Routine Description:
|
||
|
|
|
||
|
|
This function obtains the Session Key, allocates an Cipher Key
|
||
|
|
structure and returns the key.
|
||
|
|
|
||
|
|
Arguments:
|
||
|
|
|
||
|
|
ObjectHandle - Handle from an LsaOpen<ObjectType> call.
|
||
|
|
|
||
|
|
SessionKey - Receives a pointer to a structure containing the
|
||
|
|
Session Key in which the memory has been allocated via
|
||
|
|
MIDL_user_allocate().
|
||
|
|
|
||
|
|
Return Value:
|
||
|
|
|
||
|
|
NTSTATUS - Standard Nt Result Code
|
||
|
|
|
||
|
|
STATUS_INSUFFICIENT_RESOURCES - Insufficient system resources
|
||
|
|
(e.g memory) to complete the call.
