Module xor 

XOR encryption algorithm implementation.

This module provides a simple XOR-based encryption algorithm. While not cryptographically secure, it is fast and suitable for basic obfuscation of secrets in compiled binaries.

Algorithm

The Xor algorithm uses a single-byte key that is XOR’d with each byte of the plaintext. The same operation is used for both encryption and decryption (XOR is its own inverse).

Types

• Xor<KEY, D>: The main algorithm type with const generic key and drop strategy
• ReEncrypt<KEY>: A drop strategy that re-encrypts data on drop

Example

use const_secret::{
    Encrypted, StringLiteral,
    drop_strategy::Zeroize,
    xor::{ReEncrypt, Xor},
};

// Zeroize on drop (default)
const SECRET: Encrypted<Xor<0xAA, Zeroize>, StringLiteral, 5> =
    Encrypted::<Xor<0xAA, Zeroize>, StringLiteral, 5>::new(*b"hello");

// Re-encrypt on drop
const SECRET2: Encrypted<Xor<0xBB, ReEncrypt<0xBB>>, StringLiteral, 6> =
    Encrypted::<Xor<0xBB, ReEncrypt<0xBB>>, StringLiteral, 6>::new(*b"secret");

fn main() {
    let s1: &str = &*SECRET;
    assert_eq!(s1, "hello");
     
    let s2: &str = &*SECRET2;
    assert_eq!(s2, "secret");
}

ReEncrypt

Xor

An algorithm that performs XOR encryption and decryption. This algorithm is generic over drop strategy.
