| Introduced in **Filter Foundry 1.7.0.8** |
| Obfuscation version 5 is the same as version 4, but there is a constraint |
| that the seed must be equal to the hash of the deobfuscated PARM. |
| that the seed must be equal to the CRC32b checksum of the deobfuscated PARM. |
| This is done to check the integrity of the deobfuscation. |
| Also, the xor-shifting is intentionally incompatible with version 4 |
| to avoid downgrade-attacks. |
| (to avoid downgrade-attacks) by XORing the initial seed with 0xFFFFFFFF. |

| (None) |
| Minor priority stuff or ideas |
| 13,8 → 13,6 |
| * Filter Factory is much faster than Filter Foundry (example rad.afs). Why?! |
| * Why doesn't the OpenWatcom files have a PE checksum? |
| * When a filter is created obfuscated and you click "Make" again, should then be the "obfuscate" checkbox be checked again? |
| * The filter `r*(y&1)` looks horrible when you zoom out! |
| 57,7 → 55,10 |
| * Check why the plugin crashes Premiere 5 (called in image filter mode; obviously not as transition filter) |
| * Cosmetics: Include a plugin-like-icon as icon #1 so that there would be a good icon in case some apps try to display an icon from the 8BF file? |
| (Attention: make_win.c deletes icon #1 because it thinks that it is the exclamation icon, so this needs to be changed then) |
