pub struct CxParams {
    pub even_branch_perm: [u8; 8],
    pub odd_branch_perm: [u8; 6],

Available on crate features kirikiri and kirikiri-arc only.

Represents the configuration parameters for the WAMSOFT Cx encryption scheme.

This structure corresponds to the 0x20-byte memory block found at ecx + 0x3020 (or passed to CxLoadParams). It contains the permutation tables for VM instruction generation, algorithm selection flags, and encryption constants.

Fields

even_branch_perm: [u8; 8]

The permutation table for the “Even” branch of the VM code generation. Maps to EvenBranchOrder on GarBRO (Case 0-7).

odd_branch_perm: [u8; 6]

The permutation table for the “Odd” branch of the VM code generation. Maps to OddBranchOrder on GarBRO (Case 0-5).

prologue_perm: [u8; 3]

The permutation table for the Prologue of the VM code generation. Maps to PrologOrder on GarBRO (Case 0-2).

flags: u8

Configuration flags.

• Bit 7 (0x80): Random Algorithm Type (0 = Xoroshiro128PlusPlus, 1 = Xoroshiro128StarStar).
• Bit 0 (0x01): ControlBlock generate mode (0 => NOP, 1 => XOR)

mask: u16

The encryption mask used in the key calculation.

offset: u16

The encryption offset used in the key calculation.
