Function randomize_capitalization 

Source 
pub fn randomize_capitalization(input: &str) -> String
Expand description

Applies random capitalization to each letter in the input string.

Each alphabetic character has a 50% chance of being uppercase or lowercase, creating unpredictable case patterns. Non-alphabetic characters (numbers, spaces, punctuation) are preserved unchanged.

§Use Cases

  • Red Team: Bypass case-sensitive filters and detection systems
  • Blue Team: Test case-insensitive input validation
  • General: Create visually distinctive text for testing purposes

§Examples

use redstr::randomize_capitalization;

let result = randomize_capitalization("hello world");
// Example output: "HeLlO wOrLd" or "hElLo WoRLd" (varies each run)
assert_eq!(result.len(), "hello world".len());

// Numbers and symbols are preserved
let result2 = randomize_capitalization("test123");
assert!(result2.contains("123"));
