| 51 | Header file for secure malloc and free routines used by the Counterpane | |
| 52 | PRNG. Use this code to set up a memory-mapped file out of the system | |
| 53 | paging file, allocate and free memory from it, and then return | |
| 54 | the memory to the system registry after having securely overwritten it. | |
| 55 | Details of the secure overwrite can be found in Gutmann 1996 (Usenix). | |
| 56 | Trying to explain it here will cause my head to begin to hurt. | |
