* The following code handles the storage of PKCS 11 modules used by the
|

* NSS. For the rest of NSS, only one kind of database handle exists:
|
||||
*
|
||||
* SFTKDBHandle
|
||||
*
|
||||
* There is one SFTKDBHandle for each key database and one for each cert
|
||||
* database. These databases are opened as associated pairs, one pair per
|
||||
* slot. SFTKDBHandles are reference counted objects.
|
||||
*
|
||||
* Each SFTKDBHandle points to a low level database handle (SDB). This handle
|
||||
* represents the underlying physical database. These objects are not
|
||||
* reference counted, and are 'owned' by their respective SFTKDBHandles.
