| crackme|custom_vm:onion layer |
My guess is that the VM is just one onion layer. The real hard part is after it.
key -> VM/group mixer -> 5-round AES -> SHA-256 layers -> XOR mask -> FRZ{...} check
The annoying part is that there doesn’t seem to be a normal “compare key to stored value” check. It just generates bytes from the key and checks if the final result looks like a valid FRZ{...} flag. |
