---|
[169] | 37 | * The regfi library is a read-only NT registry library which serves as the main |
---|
| 38 | * engine behind the reglookup tool. It is designed with digital forensic |
---|
| 39 | * analysis in mind, but it should also be useful in other tools which need to |
---|
| 40 | * efficiently traverse and query registry data structures. |
---|
| 41 | * |
---|
| 42 | * The library is broken down into four main parts, the |
---|
| 43 | * @ref regfiBase "Base Layer", which any code dependent on the library will |
---|
| 44 | * likely need to rely on, as well as three main functional layers: |
---|
| 45 | * @li @ref regfiIteratorLayer |
---|
| 46 | * @li @ref regfiGlueLayer |
---|
| 47 | * @li @ref regfiParseLayer |
---|
| 48 | * |
---|
| 49 | * Most users will find that a combination of the Base Layer and the Iterator Layer |
---|
| 50 | * will be sufficient for accessing registry hive files. Those who are wiling |
---|
| 51 | * to dive deep into registry data structures, for instance to recover deleted |
---|
| 52 | * data structures or to research Windows registry behavior in detail, will |
---|
| 53 | * find the Parse Layer to be quite useful. |
