GIMPLE obfuscator for C, C++, Go, ... all supported GCC targets and front-ends that use GIMPLE.
``` $ cat bug.c #include #include static void AddMatch(size_t distance, size_t len) { } int target(size_t min_length) { AddMatch((min_length ? 68 : 4), min_length + 1); return 0; } $...
Example usage: ```c __attribute__ ((obfus("nobcf"))) __attribute__ ((obfus("fla"))) void make_kn(unsigned char *k1, const unsigned char *l, int bl); ```
Rather than applying to a percentage of the binary or the entire binary, obfuscate selectively (or force the obfuscation of a specific function)
Hello, I try to fla process the following function, ``` void make_kn(unsigned char *k1, const unsigned char *l, int bl) { int i; unsigned char c = l[0], carry =...
Currently the BCF "junk" is a GIMPLE NOP which is pretty ineffective at deterring reversing by itself (since it is clear which block is the opaque path)

Bitwise operators are supported for now, also support addition and subtraction for INTEGERS ONLY.
