    }())

Obfuscates a string literal at compile time.

The string is encoded at compile time and decoded at runtime on each access. Returns a promeki::String containing the original plaintext.

Parameters

str	The string literal to obfuscate.

PROMEKI_OBFUSCATE_SEED

#define PROMEKI_OBFUSCATE_SEED

Value:

     ::promeki::fnv1a(__DATE__ __TIME__))

Combines FILE, LINE, DATE, and TIME into a unique per-site seed.
