Data Obfuscation

Source: lib/Transforms/Data/

Flag	Pass	Effect
-kagura-str	StringEncryption	XOR-encrypts narrow string literals; lazy decrypt on first access
-kagura-str-aes	StringEncryptionAES	AES-128-CTR string encryption (requires runtime)
-kagura-string-split	StringSplit	Fragments long string literals (≥16 bytes) into multiple smaller globals; recombines at runtime on first use
-kagura-wstr	WideStringEncryption	XOR-encrypts wide strings (wchar_t / char16_t / char32_t) and CFString buffers
-kagura-co	ConstantObfuscation	Replaces integer constants with MBA expressions
-kagura-sub	Substitution	Replaces arithmetic/bitwise ops with equivalent MBA
-kagura-genc	GlobalEncryption	Encrypts private integer globals; inline XOR at load sites
-kagura-mvo	MemoryValueObfuscation	XOR-encrypts alloca'd integer locals at every store/load site
-kagura-pe	PointerEncryption	XOR-encrypts alloca'd pointer variables to defeat memory-dump analysis
-kagura-cse-break	CSEBreak	Duplicates shared SSA expressions so decompilers cannot re-fold them via CSE recovery

For protecting game-runtime values (HP, currency, etc.) at the C++ level, see Game Protection — Protected<T> complements kagura-mvo by adding a runtime shadow-copy integrity check.
