Detailed Description

template<size_t N, uint64_t Seed>
class ObfuscatedString< N, Seed >

Compile-time string obfuscation.

Strings wrapped with the PROMEKI_OBFUSCATE macro are encoded at compile time so the plaintext never appears in the binary. Each call site gets a unique key derived from the file name, line number, and build timestamp.

The encoding applies four operations per byte (XOR, modular add, bit-rotate, XOR) with 64-bit cipher-block-chaining so each output byte depends on the full history of all previous bytes. The per-byte key stream is derived from a splitmix64 finalizer, and the 64-bit CBC state is advanced with a multiply-xorshift step after each byte.

Usage:

String value = PROMEKI_OBFUSCATE("my_secret");

Template Parameters

N	Size of the string literal (including the null terminator).
Seed	Unique per-site seed derived from file, line, and build time.

Constructor & Destructor Documentation

ObfuscatedString()

template<size_t N, uint64_t Seed>

consteval ObfuscatedString< N, Seed >::ObfuscatedString ( const char(&)  str[N] )

inline

Encodes a string literal at compile time.

The constructor is consteval, guaranteeing that encoding happens entirely at compile time and the plaintext literal is never emitted into the binary.

Parameters

str	The string literal to obfuscate.

Member Function Documentation

decode()

template<size_t N, uint64_t Seed>

String ObfuscatedString< N, Seed >::decode ( ) const

inline

Decodes the obfuscated data back to the original string.

Returns

The decoded plaintext as a String.

operator String()

template<size_t N, uint64_t Seed>

ObfuscatedString< N, Seed >::operator String ( ) const

inline

Implicit conversion to String via decode().

Returns

The decoded plaintext as a String.
