◆ transform_t

using theo::obf::transform::transform_t = typedef std::function<std::size_t(std::size_t, std::uint32_t)>

lambda function which takes in a 64bit value (relocation address) and a 32bit value (random value used in transformation).

◆ generate()

std::vector<std::uint8_t> theo::obf::transform::generate	(	xed_decoded_inst_t *	inst,
		recomp::reloc_t *	reloc,
		std::uint8_t	low,
		std::uint8_t	high
	)

inline

generate a sequence of transformations given an instruction that has a relocation in it.

Parameters

inst	instruction that has a relocation in it.
reloc	meta data relocation object for the instruction.
low	lowest number of transformations to generate.
high	highest number of transformations to generate.

◆ operations

std::map<xed_iclass_enum_t, operation_t*> theo::obf::transform::operations

inline

Initial value:

= {
    {XED_ICLASS_ADD, add_op_t::get()},
    {XED_ICLASS_SUB, sub_op_t::get()},
    {XED_ICLASS_ROL, rol_op_t::get()},
    {XED_ICLASS_ROR, ror_op_t::get()},
    {XED_ICLASS_XOR, xor_op_t::get()}}
