| 7 * | |
| 8 * SFTKDBHandle | |
| 9 * | |
| 10 * There is one SFTKDBHandle for each key database and one for each cert | |
| 11 * database. These databases are opened as associated pairs, one pair per | |
| 12 * slot. SFTKDBHandles are reference counted objects. | |
| 13 * | |
| 14 * Each SFTKDBHandle points to a low level database handle (SDB). This handle | |
| 15 * represents the underlying physical database. These objects are not | |
| 16 * reference counted, and are 'owned' by their respective SFTKDBHandles. | |
