Anonymizer takes an input string, finds all characters that are letters or digits, shuffles them (randomizes their order), and then puts them back in their original positions. As a result, characters like @, ., +, -, _, and any other symbols remain fixed in place, and only letters (A-Z, a-z) and digits (0-9) get shuffled around.

Result

• Letters and digits within the string are shuffled, so their positions relative to each other are randomized.
• All non-alphanumeric characters (such as punctuation and symbols) remain in place.
• The overall string length and positions of special characters do not change, ensuring only the letters and digits are scrambled.

Example

• Before: "john.doe+test@example123.com"
• After: Something like "hjon.eod+ttes@exbmpla312.ocm" (your output will vary each time you run it, due to randomization).
