| Defined in **ff.h**, implemented in **make.c**: |
| |
| void obfusc(PARM_T* pparm); |
| void obfusc(PARM_T* pparm, unsigned int seed); |
| void deobfusc(PARM_T* pparm); |

| ### Obfuscation "Version 4" |
| |
| Introduced in **Filter Foundry 1.7.0.7** [08-Aug-2021] |
| |
| It is not compiler-dependant, but different between every standalone filter. |
| |
| The binary code of the 8BF file will be manipulated during building |
| in order to store the seed into the `deobfusc()` function. |
| This allows that 32 bit and 64 bit filters are "cross built". |
| |
| Algorithm: XOR shift like in version 2, but the seed is individual for |
| each individual built standalone filter. |
| |
| The value "4" will be stored at position 0x30 (this field is not used in the `PARM` resource). |

| Introduced in **Filter Foundry 1.7.0.5** [30-Jul-2021] |
