Hide Win32 API imports from your binary's Import Address Table:

constexpr uint32_t HashString(const char* str) {
    uint32_t hash = 0x811c9dc5;
    while (*str) {
        hash ^= (uint8_t)*str++;
        hash *= 0x01000193;
    }
    return hash;
}

// Usage in code:
FARPROC pVirtualAlloc = GetExportByHash(hKernel32, HashString("VirtualAlloc"));

Because HashString is evaluated by the compiler via constexpr, the string "VirtualAlloc" is never compiled into the binary, only the hash 0x4A1F3B20!

Pair this with a custom PEB module list iterator to eliminate GetProcAddress and LoadLibrary from imports.

Clean FNV-1a constexpr hash. Clean and elegant.
