VORTEX — Compile-Time Obfuscation

Ever run strings on a binary and instantly spot API keys, error messages, or internal logic? VORTEX makes that impossible.

It's a pure C11 header library that encrypts string and numeric constants at compile time — before your binary is ever written to disk. No runtime keys stored in memory. No external dependencies. Stack-only allocation.

The cipher is two-tiered: a global seed derived from your build date shapes an S-box, while a per-call-site key (based on __FILE__, __LINE__, and __TIME__) produces unique encryption per string. The result: identical source strings produce completely different binary blobs at different call sites.

Usage is a single macro:

OBF_WITH(secret, "Bearer sk-...") {
     send_request(secret); // zeroed on scope exit
}

float pi    = OBF_FLOAT(3.14159265f);
double gravity = OBF_DOUBLE(9.80665);
size_t off    = OBF_OFFSET(0xfa);
int port     = OBF_INT(8443);
OBF_STRING(secret, "xK9#mP2$qR7!wL4@"); // printf(secret)
